A Manual
of Style

The pattern is borrowed from writers who have long kept their methods visible: Gwern, Craig Mod, Robin Sloan. The goal is not a reveal of trade secrets. It is continuity. What is written on the site uses the same vocabulary, across every page. What is drawn uses the same visual grammar. What is designed uses the same five colors and two typefaces. The rigor is not cosmetic. It is how the framework stays coherent across blog posts, diagrams, newsletter issues, and any future extension.

If you are a reader trying to understand how the pieces fit together, this is the map. If you are a future collaborator, this is the ruleset.

The site runs on two typefaces. Cormorant Garamond, a contemporary revival in the Claude Garamond tradition, carries display roles: page titles, section headings, post titles, italic editorial pulls. Inter carries body text and interface elements. The serif is elevated and warm. The sans is neutral and quiet. The contrast between them is the typographic heart of the site.

Italic Cormorant in the accent color is used for single words of emphasis inside display type, never across full sentences. It carries a single focal weight on each page and should never feel decorative.

The palette is five colors. Nothing else. Every page, every diagram, every decorative accent lives inside this range.

Cream is the body background for public pages. Dark is the deep neutral used for navigation, footers, inverted sections, and the entire private lab. Accent, a warm terracotta, carries emphasis: italic display text, active link states, the single focal mark on each page. Muted is secondary text. Stone is a subtle third neutral used for fills and soft dividers.

Heading sizes move fluidly with viewport width using clamp, so the hierarchy holds its proportions from mobile to desktop without intermediate breakpoints. Page titles sit largest at roughly 3 to 7rem. Section titles drop to around 2 to 3.2rem. Body text is 0.875 to 1rem Inter at weight 300, line height 1.85. Reading measure is constrained to roughly 720 to 780 pixels on body-heavy pages to keep the line comfortable at arm's length.

No second sans. No second serif. No gradient heavier than the soft radial that lives in the top right of every dark header. Consistency across the site is the design.

Everything the site says about mindfulness in tennis resolves to three core skills, one cross-skill amplifier, and one shared territory they are all applied to. Concentration directs attention. Sensory Clarity detects and distinguishes within experience. Equanimity allows whatever arises. Interest amplifies all three simultaneously. The sense categories, visual, auditory, and somatic, are the ground these skills operate on. These are the load-bearing terms. Wherever they appear, in blog posts, diagrams, newsletter issues, LinkedIn posts, or any other written output, they mean exactly what is defined below. Alternative phrasings dilute the framework, so alternatives are not used.

For the full articulation of each skill, with the tennis language grounded in each framework category, see the framework hub.

Concentration

Concentration is the ability to direct attention to what matters, hold it there for as long as the situation requires, and redirect it when needed. It is where attention goes, for how long, and with what reliability. It is not sensory clarity, which is the resolution of what attention lands on. It is not equanimity, which is the relationship to what is experienced. It is the attentional capacity itself. See the full treatment in Concentration in Tennis.

Sustained attention. The capacity to hold attention on an object or process over an extended period. Keeping focus on the ball throughout a long rally. Staying with a drill for a full practice block. One mode of concentration, not the defining quality of it.

Momentary attention. The capacity to land attention precisely on an object for a brief window, sometimes a fraction of a second, with full presence. Noticing the contact point on the racket at the moment of impact. Catching the shift in the opponent's shoulder before they strike. Frequently more relevant in match play than sustained attention, because tennis is a sport of rapid attentional shifts.

Distraction resistance. The capacity to keep attention on the chosen object when competing stimuli pull at it. The crowd, the score, a bad line call, fatigue, inner talk. The strength of the attentional hold against interference. Distinct from sustained attention: sustained is about duration, distraction resistance is about stability under pull.

Selective attention. The capacity to choose, from the field of available objects, the one that matters most in this moment. Distinct from distraction resistance: resistance is holding against pull, selective attention is choosing where to place attention in the first place, and choosing the object correctly.

Active and passive stance. Active is deliberately directing or holding attention somewhere, the effort of will to bring attention to a chosen object and keep it there. Passive is allowing attention to move where it is drawn, not an absence of concentration but a different kind of attentional engagement where the player is not forcing direction. Both are trained. Active dominates in early development and in high-pressure situations. Passive emerges at higher levels, where trained patterns have made attention move correctly by its own accord.

Zooming. The capacity to narrow or widen the attentional cone across any sense category. From a single fingertip to the whole body. From the ball seam to the full court. From one sound to the full auditory field. Distinct from choosing what to attend to: that is selective attention. The size of the cone around the chosen object is zooming.

Orientation. Deliberately turning attention toward what is pulling it, or anchoring attention away from it. The choice of direction, toward or away, is itself a trainable capacity. Turning toward a difficult experience is one form of concentration training. Anchoring attention away from an intrusive pull is another. Knowing which the situation calls for is the skill.

Contact strategies. Three distinct patterns of attentional contact. Single focus: all attention on one experience, held continuously through a practice. Systematic: attention moves in a deliberate sequence, a toggle between two objects, a smooth sweep through a region of the body or across the court, in discrete steps or as continuous flow. Free exploration: attention moves without a predetermined order, within one sense category if useful, following curiosity.

Bear down and ease up. Regulation of attentional effort. Bear down is increasing intentional effort when the situation demands more than the current level of engagement provides. Ease up is reducing effort when over-trying is creating tension and the attempt to concentrate is itself tightening attention past what is useful. Over-effort in concentration can cost performance as much as under-effort.

Continuity of concentration is a separate dimension from the four subskills and five strategies. It is reliability across time. A player can have strong individual subskills and inconsistent continuity, or moderate subskills and high continuity. What continuity means in tennis is not continuous focus on one object. It is the reliability with which the player can direct attention where it needs to go, for as long as it needs to be there, across the full duration of a match.

Sensory Clarity

Sensory clarity is the ability to notice what is actually happening, in the body, in the environment, in the moment, with enough precision and speed to act on it. It is the resolution of what attention lands on. High sensory clarity means what is noticed is detailed, accurate, and arrives in time. Low sensory clarity means attention is present but what it picks up is vague, approximate, delayed, or misidentified. See the full treatment in Sensory Clarity in Tennis.

A point that matters for every experience the framework covers: experience is treated as process, not thing. Nervousness is not an object to be located. It is a process of sensations rising and shifting in the body across time. The same applies to tension, inner talk, attention itself. Sensory clarity resolves processes into their detectable features, not objects into their properties.

These are the qualities that can be detected with increasing precision within any experience, across any of the six sense poles. They are not categories of experience. They are resolutions within experience.

Location is where the experience is situated. Size is how much space it occupies. Shape is its form. Border is whether it has a clean, clearly defined edge or a diffuse, washed-out boundary. Motion is whether it is static or moving, and in what direction. Temporal is when it arises, how long it lasts, and when it disappears. Intensity is how strong it is on a spectrum from subtle to vivid. Hedonic tone is whether it is pleasant, unpleasant, or neutral, the foundational dimension because it is what connects sensory clarity to equanimity. Interaction is how experiences relate to and influence each other, a higher-order clarity skill that requires individual experiences to be detected clearly before their relationships become visible.

Meta-awareness is sensory clarity turned toward the field of attention itself. Where the nine dimensions apply to whatever experience attention lands on, meta-awareness applies to attention itself. The skill is seeing where attention currently is. It is not returning attention. That is concentration. The return becomes possible only because meta-awareness first detected that attention had moved, and where it had gone. Conflating the two collapses a perception skill into an action skill and misses what is actually being trained.

Equanimity

Equanimity is the ability to allow experience to be as it is, without suppression, clinging, or dismissal. It is not calmness. It is not indifference. It is not passivity. It is a trained relationship to experience that does not add unnecessary struggle on top of what is already there. See the full treatment in Equanimity in Tennis.

Every experience in a match sits somewhere on a spectrum. On one end it is unpleasant. On the other it is pleasant. In the middle it is neutral. The natural response to each is predictable: avoid and suppress what is unpleasant, cling to what is pleasant, dismiss what is neutral. Equanimity changes that relationship in three directions, each a separate trainable capacity.

Allowing unpleasant. The capacity to allow difficult experience to be present without immediately trying to make it stop. Pre-match nervousness. Frustration after an error. The discomfort of fatigue. The desperation of being down a break in the third set. Allowing unpleasant does not mean accepting defeat. It means allowing the experience of being behind without adding the second layer of fighting the experience of being behind.

Non-clinging to pleasant. The capacity to allow pleasant experience to come and go without grasping at it. A run of good points. A feeling of confidence. Momentum building. Clinging to pleasant experience introduces a different kind of interference: the fear of losing what is going well. That fear changes shot selection, tightens the swing, and puts the player into a protective mode that was not serving them when they were playing freely.

Non-dismissal of neutral. The capacity to stay present to experience that is neither pleasant nor unpleasant. The neutral rallies. The routine serve. The long stretches of a match that are neither dramatic nor comfortable. In tennis, neutral experience is where most of the match actually takes place. Players who dismiss it spend the majority of their time not fully present and then wonder why they are not sharp when the important points arrive. The quiet third direction, often left out of mental performance work.

These are three genuinely separate capacities. Training one does not automatically develop the others. A player who has worked extensively on allowing unpleasant may still have low non-clinging and be consumed by anxiety when things are going well.

Equanimity operates at two levels simultaneously, both trainable independently.

Foreground equanimity. Allowing an experience the player is deliberately paying attention to. The nervousness being noticed directly. The fatigue being tracked. The more commonly understood form, developed through direct exposure to the experiences that typically produce resistance.

Background equanimity. Allowing an experience that is present but not being deliberately attended to, or that the player is trying not to attend to. The crowd noise while focused on the ball. The anger from the last point while playing the next one. The tightness in the shoulder while reading the opponent's position. Low background equanimity drains concentration passively, and the player cannot identify what is costing them because they were never directly attending to it. Background equanimity is arguably more important for match performance than foreground equanimity, because it operates continuously and invisibly.

Interest, the cross-skill amplifier

Interest is genuine curiosity toward experience. It is the one factor in the framework that strengthens all three skills simultaneously. When a player is genuinely curious about what nervousness feels like, its location, shape, intensity, how it changes across a match, the nervousness becomes something to explore rather than something to escape. The allowing follows. Curiosity also sharpens detection, giving sensory clarity something real to resolve. And it holds attention in place without requiring force, easing the load on concentration. Interest can be trained deliberately, by bringing genuine curiosity to any experience, including the most difficult ones.

The sense categories, the shared territory

The sense categories are where the three skills land. Concentration directs attention into them. Sensory Clarity detects and distinguishes within them. Equanimity allows whatever arises in them. They are not a sub-structure of any one skill. They are the shared ground all three operate on.

All experience falls into one of three categories. Each divides into outer and inner. Each pole divides into active and restful.

Visual outer. Anything seen: ball trajectory, opponent position, court geometry, body language, the lines. Visual inner. Mental images: replaying the last error, seeing the next shot before it happens, visualizing the toss.

Auditory outer. Anything heard: ball contact sound, opponent footwork, crowd noise, own breathing, wind. Auditory inner. Inner talk: self-instruction, self-criticism, internal commentary running before, during, and after points.

Somatic outer. Sensations in the body whose source is physical or physiological: racket in the hand, feet on the court, breath, heartbeat, muscle fatigue, grip pressure, wind on skin, heat, sweat, taste, smell. Anything the body physically feels from the environment or from its own physical state. Somatic inner. Sensations in the body whose source is emotional rather than physiological: the felt quality of fear, anger, joy, excitement, anxiety, frustration, confidence, disappointment. The felt quality can be identical to an outer somatic sensation, which means the distinction is by source, not by feeling.

Physical body sensations and emotional body sensations occupy the same region, the body, and often have the same felt quality. The distinction is by source, not by feeling. A racing heart from a long rally is outer somatic. A racing heart from fear before a big serve is inner somatic. A churn in the stomach from something eaten at lunch is outer somatic. The same churn from nervousness before walking on court is inner somatic. The categorization is first-person. A spectator cannot see it, and a heart rate monitor cannot tell the difference. The distinction lives in the player's own perception, which is why it is a sensory clarity skill rather than something a coach can verify from the outside. Misidentifying the category means responding to the wrong thing. A player who treats pre-match anxiety, inner somatic, as a physical problem will try to stretch it away or slow the breath to eliminate it. A player who detects it as emotional relates to it differently. The distinction is non-standard and consequential, and it matters everywhere the framework touches competitive emotion.

Active experience is vivid, present, and tends to demand attention. Restful experience is quiet, subtle, or absent. Both are real. Both are trainable attentional objects. Noticing the absence of tension in the arm is as trainable as noticing its presence. Noticing inner silence is as trainable as noticing inner talk. Subtlety lives in the restful poles, and subtlety is where the fine detail that separates good decisions from great ones tends to reside.

Motor imagination, a practice technique

A practice technique, not a capacity. Motor imagination is a way to train, not a thing being trained, and it sits alongside the framework rather than inside it. In the Unified Mindfulness system, the motor side of experience already lives in the Express quadrant, where attention is paid to the automatic nature of motor expression. Separately, the Positivity quadrant and Metta practice involve the deliberate cultivation of positive experience, including inner visualizations, affirmations, and pleasant emotional body sensations. The extension is the application of that Positivity cultivation principle to inner somatic motor experience specifically, for athletic training. Not observing motor expression as it arises, but deliberately evoking and imagining the felt quality of movement, what a clean forehand feels like, what good timing feels like, what a fluid serve feels like. These are inner somatic experiences of movement, imagined deliberately, and used as training anchors.

The framework terms above are the precise architecture. Tennis players do not think in those terms during a match. They think about grip pressure, the toss, contact feel, whether the arm is free, whether they are late to the ball. The site writes to players in player language. The framework provides the architecture underneath. Neither replaces the other.

Every phrase used in player-facing content is checked against a canonical phrasing reference. Three layers:

Used as written. Phrases that are already precise and appear on the site exactly as players say them. The arm is relaxed. The arm is tight. The timing is right. I am late to the ball. Point of contact. The toss. Reading the opponent. Creating the angle. Player vocabulary that does not need translation.

Require unpacking, not replacement. Authentic player phrases that stay as the surface language, but are connected to the framework mechanism underneath whenever the writing goes explanatory. I choke. I feel nervous. I feel confident. I don't trust the shot. I lost my focus. I am guiding. I am not feeling it. The timing feels off. I lack confidence. I am unsure what to do. These remain the voice. The framework arrives underneath, not instead of them.

Never used. Phrases that are either too vague to be useful or carry the wrong associations from generic mindfulness and sports psychology writing. Be present. Live in the moment. Mental toughness. Mental strength. Positive self-talk. Emotional control. Managing emotions. Staying calm. Clear your mind. Negative emotions. Positive emotions. Growth mindset. Trust the process. In the zone. These phrases do not belong in this voice or this framework. Where a reader might expect one of them, the site uses the specific mechanism instead.

The organizing principle is simple. Player language is the surface. Framework precision is what sits underneath. Accessibility comes from the surface. Precision comes from what holds it up.

Diagrams on this site follow a specific philosophy. The goal is one unified interactive surface, not separate boxes connected by arrows. The interaction should feel like touching a living system, not adjusting settings on a control panel.

No separate boxes with arrows between them. No standalone slider controls. No static diagrams unless the concept is genuinely too simple to warrant interaction. Instead, a single unified canvas or surface where the user manipulates one thing and the whole system responds. Radar and spider shapes that deform when dragged. Single shapes that change color and size in response to input. Canvas-based drawing that responds to touch and mouse.

State transitions are animated and sequenced, not simultaneous. When multiple elements change together, they lead and follow each other in a way that reflects the actual relationships between them. Extreme states like flow and overwhelm are shown with dedicated buttons that animate the system to those states, rather than requiring the user to drag everything manually into position.

Depth on one scenario beats shallow exploration of many. When a diagram is already information-dense, adding variety dilutes rather than enriches. A single strong example that goes deep teaches more than three or four shallow ones that force the viewer to recalibrate at every switch. The exception is when the scenarios themselves are the teaching material, where different situations demand different subskills, or where a genuine contrast, such as sharp border versus diffuse border, is the point.

Every diagram works identically on mobile and desktop. Canvas-based approaches with touch and mouse event handling scale naturally to any screen size without layout changes, which is why they are preferred.

The main site uses a small, deliberate set of animations. Each one is tied to a specific surface and does one thing well. Nothing blinks, nothing parallaxes, nothing loops past the point of utility.

Logo breathe. The Straka mark in the navigation pulses gently between 85 and 100 percent opacity on a four-second cycle. Stops on hover.

Nav underline draw. A fine accent line grows left to right underneath navigation links on hover, using a CSS pseudo-element.

Magnetic hover. Primary and ghost buttons drift subtly toward the cursor on hover and snap back on leave. Disabled on touch devices.

3D tilt. Service cards tilt toward the cursor in three dimensions on hover. Very subtle. Disabled on touch devices.

Counter roll. Large numeric credential values count up from zero when the section enters the viewport, using a cubic ease-out. Fires once.

Court line draw. The court diagram on the home page animates its lines in sequence over roughly 3.5 seconds when scrolled into view. Baseline first, then doubles sidelines, then singles sidelines, then the net drops, then service lines, then an accent square at the baseline intersection.

Variable-speed typewriter. Used on the blog index title. Types briskly through the opening phrase, pauses, then types the italic second line more deliberately. Cursor blinks, then fades, then the subtitle rises.

Blog-post diagrams use scroll-triggered animations via IntersectionObserver. Elements animate in when they enter the viewport at threshold 0.15 to 0.2. Animations fire once and unobserve. Never loop. The standard reveal vocabulary: fadeSlideIn, fadeSlideRight, cardDropIn, stageIn, posIn, layerIn. Sequential animations stagger by 0.1 to 0.35 seconds per element. The choking cascade diagram uses pulse and spread, where each step activates with a ripple spreading outward from the left border.

Title animations are tied to the meaning of each post. The word choke gets squeezed from the center outward. A title about pressure shudders briefly before stabilizing. A title about vagueness fades in slowly, as if dissolving into visibility. A title about indecision types normally but hesitates on the decisive word, briefly starts another, then corrects. A title about drill integration arrives clean and methodical, each word in precise sequence.

Any element that starts invisible and relies on IntersectionObserver to reveal is wrapped in a safety net: a lower threshold of 0.1, a setTimeout fallback that checks position independently, and a default reveal for browsers without observer support. Silent failures from observer timing are prevented by design.

All interactive animations are disabled on touch devices.

The voice is consistent across every page: precise, warm, direct, authoritative. Not generic wellness language. Not sports psychology cliché. The distinction between a skill, which is a trainable capacity, and a strategy, which is a way that skill is deployed, is maintained throughout. Sustained attention is a skill. Bear down and ease up are strategies. The two are not interchangeable.

No dashes anywhere in the prose. Sentences restructure around commas, around the word and, or into shorter clauses instead. The rule sounds cosmetic. It is not. It forces the writing toward sentence shapes that earn their own rhythm rather than leaning on punctuation to hold a thought together.

Experience is written about as process, not thing. Nervousness is not an object to be located. It is a process of sensations rising and shifting across time. Tension is not a thing in the shoulder. It is a process of muscular and emotional activation that changes across the match. Inner talk is not a noise to be silenced. It is a stream with texture, onset, and fading. Sensory clarity resolves processes into detectable features, not objects into their properties. The prose reflects this where relevant.

Claims are specific or they are rewritten. Where a reader might expect the phrase mental toughness, the site names the actual capacity: distraction resistance, equanimity with pressure, the ability to commit to the swing on a big point. Where a reader might expect staying calm, the site names what is actually happening: the arm stays relaxed even when the body is nervous. Where a reader might expect emotional control, the site says the opposite of what that phrase implies: not suppression, but allowing the experience without it driving the shot.

Player language is the surface. Framework precision is what sits underneath. Blog posts and newsletter issues use player language. Writing that goes explanatory, whether in a blog post or on the framework hub, carries the framework through.

Framework vocabulary is taught in two places. Full treatments live in the three skill posts, the framework hub, and this colophon. In passing, every canonical term in a blog post prose body carries a hover popup with a one-sentence definition and a link back to the relevant section here. The popup attaches to the first occurrence of each term per post, and subsequent uses stay as plain text. Existing hyperlinks are never interfered with. The reader gets the definition without leaving the page, and a path to the full treatment if they want more.

All photographic assets on the site use dashed, lowercase, SEO-friendly filenames. The pattern is christian-straka-headshot.jpg, christian-straka-tennis-coach.jpg, christian-straka-speaking.jpg, christian-straka-mike-bryan-atp-finals.jpg. Never camelCase. Never no-dash variants. Every HTML reference across the site expects the dashed form, and every local file matches the deployed filename so local previews work without surprises.

The editorial portrait pattern is used wherever a photograph is placed on the site, rather than a simple framed image. Asymmetric accent-colored frame lines draw in on scroll reveal. The photo rises from a small translation with a gentle fade. A grayscale filter with warm radial overlay reads the image as editorial portrait rather than snapshot. On desktop hover, the grayscale lifts over a slow transition. The pattern is reused for consistency, not decoration.

AI tools accelerated parts of the build. The frameworks, the voice, and the expertise are Christian's.
