--- version: alpha name: cal.com description: "Light product system built on #f4f4f4 with #7826b1 as the primary CTA accent. Type anchored in Cal Sans at 48px / weight 600. Extracted automatically from https://cal.com/ — rendered styles via getComputedStyle() + CSS custom properties (token-only values may not be painted)." narrative: | cal.com is built on a pure-white canvas (rgb(244, 244, 244)). The system uses rgb(120, 38, 177) as the accent for primary actions and brand signals. Moderately rounded CTAs (8px) — modern SaaS standard, neither sharp nor pill alongside Cal Sans as the primary typeface. Cal Sans is paired with Cal Sans UI Variable Light Placeholder for secondary roles. A layered elevation system (11 distinct shadows) building a clear front-to-back hierarchy. Motion is minimal — a few targeted transitions, no decorative animation. colors: background: "#f4f4f4" surface-1: "#ffffff" surface-2: "#f5f5f5" ink-muted: "#242424" ink-subtle: "#111111" primary: "#7826b1" on-primary: "#ffffff" primary-hover: "#aa61f1" hairline: "rgba(255, 255, 255, 0.03)" typography: display-xl: fontFamily: "Cal Sans, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 64px fontWeight: 600 lineHeight: 1.1 letterSpacing: 0 display-md: fontFamily: "Cal Sans UI Variable Light, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 18px fontWeight: 300 lineHeight: 1.3 letterSpacing: -0.2px body: fontFamily: "Cal Sans, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 12px fontWeight: 400 lineHeight: normal letterSpacing: 0 body-sm: fontFamily: "Cal Sans UI Variable Light, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 14px fontWeight: 300 lineHeight: 1.5 letterSpacing: -0.2px button: fontFamily: "Cal Sans, 'SF Pro Display', system-ui, -apple-system, 'Segoe UI', Roboto, sans-serif" fontSize: 12px fontWeight: 600 lineHeight: normal letterSpacing: 0 rounded: none: 0px xs: 4px sm: 8px md: 12px lg: 16px xl: 29px pill: 1000px spacing: xxs: 2px xs: 6px sm: 10px md: 12px lg: 24px xl: 48px xxl: 96px components: button-ghost: backgroundColor: "#000000" textColor: "{colors.hairline}" typography: "{typography.body}" rounded: "{rounded.sm}" padding: 12px 24px button-pill: backgroundColor: "{colors.surface-2}" textColor: "#0000ee" typography: "{typography.body}" rounded: "{rounded.pill}" padding: 4px 8px 4px 12px extracted_at: "2026-06-11T04:59:56.383Z" completeness: 65 scoreVersion: "v2" --- # Design System — cal.com > Extracted automatically by Prism from https://cal.com > Date: 2026-06-11 > Viewport: Desktop 1440x900 + Mobile 390x844 > Values are extracted, not hand-written: rendered styles via getComputedStyle() + colors declared in CSS custom properties (token-only values are marked `(token)` and may not be painted). ## 0.

Skip §11–12 unless extending. ## 1. Visual Theme & Atmosphere cal.com sits on a off-white canvas (`#f4f4f4`), a neutral foundation calibrated for sustained reading and component contrast. Headlines are set in **Cal Sans**, a sans-serif display face (the dominant type signature, e.g. "With us, appointment scheduling is easy" at 48px). Body text is set in **Cal Sans UI Variable Light**. Headlines use weight 600 for confident, assertive presence — the brand wants to be heard. Body text reads in Pure Black (`#000000`) (contrast ratio 20.1:1, well above WCAG AA). **#7826b1** (`#7826b1`) is the single high-saturation color in the system — it earns its presence only on interactive elements, making CTAs and links the unmistakable focal points against the otherwise neutral palette. Elevation is built from multi-layer shadow stacks (11 distinct) — each combines several blurred layers at varying offsets to build a clear front-to-back hierarchy. Border radius varies from pill-shaped (fully rounded) to moderately rounded elements, creating visual rhythm. The site uses a variable font with GEOM + WGHT axes, enabling precise weight/width control across the type hierarchy. **Key Characteristics:** - Background: Off-White (`#f4f4f4`) - Primary typeface: Cal Sans - Accent: #7826b1 (`#7826b1`) - Display: 64px weight 600 - Shadow system: 11 distinct elevation levels - Custom fonts loaded: Cal Sans, Manrope, Public Sans, Fragment Mono, Roboto Mono, Matter Regular, Cal Sans UI Variable Light, Matter SemiBold, Matter Medium, Paper Mono Regular, Cal Sans UI Light, Matter Bold, Cal Anim Graph 5 [MORF] Variable Regular, Matter Bold Italic, Matter Regular Italic, Inter, Inter Variable, Inter Display ## 2.

Component Stylings ### Buttons **Ghost** - Background: `#000000` - Text: `#ffffff` `{colors.hairline}` - Padding: 12px 24px - Radius: 8px - Shadow: `rgba(0, 0, 0, 0.15) 0px 4px 12px 0px` - Font: 12px weight 600 - Use: Subtle action, toolbar, nav button **Pill** - Background: `#f5f5f5` `{colors.surface-2}` - Text: `#0000ee` - Padding: 4px 8px 4px 12px - Radius: 9999px - Shadow: `rgba(34, 42, 53, 0.05) 0px 4px 8px 0px` - Font: 12px weight 400 - Use: Status pills, tags, chips ## 4b. Component Behaviors (State Matrix) ### Interaction State Narrative *State transitions extracted via Playwright simulation — exact values in the YAML matrix below.* ```yaml component-behaviors: button: default: bg: "rgb(0, 0, 0)" fg: "rgb(255, 255, 255)" shadow: "rgba(0, 0, 0, 0.15) 0px 4px 12px 0px" link: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(0, 0, 238)" badge: default: bg: "rgba(0, 0, 0, 0)" fg: "rgb(0, 0, 0)" ``` **Agent usage**: Validate generated components against this matrix. If your output's `:hover` state changes properties not listed here, you are off-brand. ## 4c. Component Vocabulary (Closed System) *This brand uses ONLY the following component vocabulary. Introducing new variants without justification breaks the system's tonal coherence.* ### Buttons - **2 shape(s)** in this system: `Ghost`, `Pill` - **DO NOT introduce new buttons variants** without justification ## 5. Layout Principles ### Layout Type **top-nav + content** ### Grid Single column, centered content ### Max Width 1200px ### Spacing System Generous spacing — editorial breathing room | Token | Value | |-------|-------| | xxs | 2px | | xs | 6px | | sm | 10px | | md | 12px | | base | 18px | | lg | 24px | | xl | 48px | | 2xl | 80px | | 3xl | 96px | ### Border Radius Scale | Name | Value | Use | |------|-------|-----| | None | 0px | No rounding | | Xs | 4px | Tiny corners (badges, micro elements) | | Sm | 8px | Buttons, inputs, small elements | | Md | 12px | Cards, containers | | Lg | 16px | Large rounded elements, pill segments | | Xl | 29px | Category strips, featured containers | | Full | 1000px | Pills, avatars, circular elements | ### Shape Language | Component | Border Radius | |-----------|---------------| | Buttons | `8px` | | Page Body | `0px` | **Shape Personality**: Moderate Rounding — Medium corners (4–12px). Modern SaaS standard, neither sharp nor pill. **Full Radius Spectrum**: 0px, 2px, 4px, 6px, 6.94px, 7px, 8px, 10px (from `allBorderRadii` scan) ## 5b. Spacing Rhythm Names **Measured section padding**: bands use ~24px internal vertical padding (up to 80px) — **compact**. (Distinct from the gap *between* sections above.) Reproduce this generous vertical breathing room; cramped spacing is the #1 tell of a cheap clone. *Named spacing tokens with explicit use cases. Use these names in YOUR code instead of raw pixels for consistency.* | Name | Value | Use case | |------|-------|----------| | **hero** | `96px` | Top/bottom of full-bleed hero sections | | **section** | `48px` | Between major bands (color change, content shift) | | **subsection** | `24px` | Within a section, between content groups | | **card** | `12px` | Card padding, list-item spacing | | **compact** | `10px` | Form fields, tight clusters, badge padding | | **micro** | `6px` | Icon-text gap, tag inner padding | **Agent rule**: NEVER hardcode raw pixel values for spacing in generated UI. Always reference these named tokens (`spacing-rhythm.section`, etc.). ## 5c. Widget & Structure Library Structural patterns extracted from the page DOM — these are the **blueprints** an agent should follow to reproduce the page architecture (not just CSS values). **3/8 structural patterns detected.** ### Hero Pattern - **Composition:** left-aligned — - **Viewport coverage:** 211px tall (not full-viewport) - **Heading:** "The better way to schedule your meetings" — 64px left-aligned - **CTAs:** none detected in hero (unusual — agent should verify) - **Clone instruction:** Reproduce the **left-aligned** layout. Use the heading font-size token at the documented size. Pair the centered text with the hero’s decorative visual (gradient / SVG / hero image — see §9b), not bare text. ### Card Grid Pattern - **Card count:** 4 cards detected - **Columns (desktop):** 3-up grid - **Card dimensions:** 518×403px (aspect 1.29:1) - **Gap:** 12px between cards - **Content:** ✗ no image + icon - **Clone instruction:** Build a 3-column grid (desktop) with cards at ~1.29:1 aspect ratio. Text/icon-only cards (no photography). ### Footer Pattern - **Columns:** 4 - **Links:** 53 total - **Height:** 664px - **Includes:** ✗ no newsletter | ✓ social icons | - **Clone instruction:** Build a 4-column footer with ~13 links per column, social media links. ## 6. Depth & Elevation | Level | Treatment | Use | |-------|-----------|-----| | Flat (Level 0) | No shadow | Page background, content blocks | | Layered (Level 1) |
`rgba(0, 0, 0, 0.15) 0px 4px 12px 0px` | Cards, elevated surfaces | | Inset (Level 2) |
`rgba(255, 255, 255, 0.15) 0px 2px 0px 0px inset` | Buttons, pressed-state elements | | Layered (Level 3) |
`rgba(36, 36, 36, 0.7) 0px 1px 5px -4px`,
`rgba(36, 36, 36, 0.05) 0px 4px 8px 0px` | Cards, elevated surfaces | | Layered (Level 4) |
`rgba(34, 42, 53, 0.05) 0px 4px 8px 0px` | Cards, elevated surfaces | **Shadow Philosophy**: Multi-layered shadow system creating natural, atmospheric depth. Each shadow level combines multiple layers for realistic elevation. ## 7. Motion & Interaction ### Keyframe Animation Catalog | Animation Name | Type | Animated Props | Use Hint | |----------------|------|----------------|----------| | `__framer-loading-spin` | Rotate / Spin | transform | Loading indicator | | `pulse` | Fade | opacity | Attention / status | ### Motion Fingerprint - **Dominant Easing**: standard CSS easings - **Animation Library**: 2 unique animations (2 total including variants) ## 8. Do's and Don'ts ### Do - Use Off-White (`#f4f4f4`) as the page background — it's intentionally not pure white - Keep font weights between 400-600 — the system uses a narrow weight range for subtle hierarchy - Use the extracted shadow patterns for elevation — they are tuned to match the brand palette - Use full-pill radius (9999px) only for specific elements (avatars, pills, toggles) - Use #7826b1 (`#7826b1`) as the primary accent — it's the brand's signature interactive color - Respect the 6px–48px spacing range — the design uses a wide scale for visual breathing room - Each card uses an icon (not photo) — the visual language is illustrative, not photographic - Use a 3-column grid on desktop — density matters for this content type - Build a content-dense footer (4 columns, ~53 links) — this site treats the footer as a sitemap, not an afterthought ### Don't - Don't use pure white (`#ffffff`) as a page background — the warm tone is part of the brand identity - Don't use weight 700 (bold) or above — 600 is the maximum weight in this system - Don't invent new shadow values — use only the extracted shadow levels - Don't apply pill radius on rectangular buttons or cards — it's reserved for specific interactive elements - Don't introduce additional saturated accent colors — the palette is intentionally controlled ## 7b. Enforceable Brand Rules *Structured Do/Don't with reasoning and validation tests. Agents can programmatically verify generated UI.* ```yaml rules: - id: brand-canvas-001 type: do rule: "Always use the page background `rgb(244, 244, 244)` as the base canvas" why: "Every component is designed to composit against this exact tone" test: "document.body.style.backgroundColor === 'rgb(244, 244, 244)'" - id: brand-accent-001 type: do rule: "Reserve `rgb(120, 38, 177)` for primary CTAs and brand-mark signals only" why: "Single chromatic assertion device — overuse dilutes meaning" test: "querySelectorAll('[style*=\"rgb(120, 38, 177)\"]').length <= 3 per fold" ``` ## 9. Responsive Behavior ### Breakpoints | Name | Width | Key Changes | |------|-------|-------------| | Mobile Large | 640px | Expanded mobile layout | | Tablet | 768px | Multi-column grids begin | | Tablet | 809px | Multi-column grids begin | | Tablet | 1024px | Multi-column grids begin | | Desktop | 1199px | Full feature layout | ### Token Diff — Desktop vs Mobile | Element | Property | Desktop | Mobile | |---------|----------|---------|--------| | heading | font-size | `64px` | `40px` | | heading | line-height | `70.4px` | `44px` | ### Collapsing Strategy - Headlines: 64px → 40px on mobile - Navigation: horizontal links → hamburger menu on mobile - Cards: multi-column → stacked vertical on mobile - Footer: multi-column → stacked single column on mobile ### Touch Targets - Buttons: 12px 24px padding - Navigation: adequate spacing between items - Interactive elements: minimum 44px touch target recommended ### Collapsing Narrative How the structural patterns adapt from desktop to mobile (extracted from both viewport extractions): - **Card grid: 3-up → 1-up** — cards stack as viewport narrows, becoming a vertical list on mobile. ## 7c. Visual Effects & Dynamic Behavior *The live/dynamic layer beyond static CSS — reproduce these, not flat substitutes. This is often what separates a faithful clone from a wireframe.* - **Clip-path shapes** — 7 non-rectangular cut(s). - **Scroll-driven reveals** — content animates in on scroll (CSS scroll-timeline). Build fade/translate reveal-on-scroll for below-fold bands. > **Motion fingerprint**: non-rectangular shapes (7), CSS scroll-driven animations ## 9b. Visual Tone & Photography **Tone:** Illustration-driven The site relies primarily on illustrations, vector art, and decorative SVG elements rather than photography. Use commissioned illustrations, icon sets, or generated graphics for clones — stock photos will feel off-brand. **Canonical Brand Image (OG):** - https://framerusercontent.com/images/pPSh5HDe1qaySb4R7xBgMHudhU.png *This is the image shown when the site is shared on social media — represents the brand visual essence.* **Aspect Ratio Distribution:** - Landscape (1.15–2.3): 2 (67%) - Portrait (<0.87): 0 (0%) - Square (0.87–1.15): 0 (0%) - Ultra-wide (>2.3): 1 (33%) **Media Format Mix:** - PNG: 1 (logos, transparent UI elements, mockups) - SVG: 5 (icons, illustrations, decorative geometry) **Average rendered image size:** 537×198px **Above-fold image count:** 0 / 3 **Decorative Patterns Detected:** - 1 radial gradient — circular color blooms used for spotlight/glow effects - 3 large decorative SVG shapes (≥200×200px, non-icon) — likely blob/illustration accents - 34 background patterns (non-photo url() backgrounds) — textures/illustrations as backdrops **Clone instruction for decorative work:** Decorative SVG accents are part of the brand — generate or source blob/illustration shapes to scatter behind content. **Imagery Guidance for clones:** - Use vector illustration as the primary visual language — photos will read as off-brand. - Maintain consistent illustration style (line weight, color palette) across the site. ## 10. Agent Prompt Guide ### Quick Reference - Background: Off-White (`#f4f4f4`) - Primary text: Pure Black (`#000000`) - Accent: #7826b1 (`#7826b1`) - Border: Translucent Pure White (3%) (`rgba(255, 255, 255, 0.03)`) - Font: Cal Sans - Body: 12px weight 400 ### Example Component Prompts - "Create a hero section on Off-White background (#f4f4f4). Headline at 64px Cal Sans weight 600, line-height 1.1, color #000000." - "Create the primary CTA button: `#7826b1` background, `#ffffff` text, 8px border-radius, 12px 24px padding, 600 weight, Cal Sans font." - "Build navigation: sticky on `#f4f4f4`. Cal Sans 16px weight 400 for links." ### Iteration Guide 1. **Canvas**: Set the light canvas to Off-White (`#f4f4f4`) — every component is composited against this exact base. 2. **Typography**: All type in Cal Sans, weight range 400–600. Never exceed 600 — heavier weights break the brand's tonal restraint. 3. **Accent**: #7826b1 (`#7826b1`) is the sole interactive color. On hover → #aa61f1 (`#aa61f1`). Use CSS transitions, not opacity/brightness filters. 4. **Spacing**: Use the `--ca-space-*` token scale (6px–48px). All padding, margin, and gap values are multiples from this scale — no magic numbers. 5. **Tokens**: Import from §11 CSS Export (`--ca-*` vars). Never hardcode hex values — always reference a token so theming remains consistent. ## 11. CSS Design Tokens Raw Export *Copy-paste ready `:root {}` block — all values extracted directly from the live site.* ```css /* Colors */ :root { --ca-background: #f4f4f4; --ca-hairline: #ffffff; --ca-surface-2: #f5f5f5; --ca-ink-muted: #242424; --ca-ink-subtle: #111111; --ca-primary: #7826b1; --ca-primary-hover: #aa61f1; } /* Typography */ :root { --ca-font-primary: "Cal Sans", system-ui, sans-serif; --ca-text-display: 64px; --ca-text-body: 12px; --ca-text-small: 14px; --ca-text-button: 12px; } /* Spacing & Radius */ :root { --ca-space-xxs: 2px; --ca-space-xs: 6px; --ca-space-sm: 10px; --ca-space-md: 12px; --ca-space-base: 18px; --ca-space-lg: 24px; --ca-space-xl: 48px; --ca-space-2xl: 80px; --ca-space-3xl: 96px; --ca-radius-none: 0px; --ca-radius-xs: 4px; --ca-radius-sm: 8px; --ca-radius-md: 12px; --ca-radius-lg: 16px; --ca-radius-xl: 29px; --ca-radius-full: 1000px; } ``` ## 13.

Reproduce these sections in order to match the site structure.* ```yaml page-skeleton: - section: hero tag: div height: 8521px width: full-bleed layout: block children: 3 - section: feature-section tag: div height: 796px width: 1200px layout: flex-column justify=center children: 1 vertical-padding: ~48px padding: "96px 12px 0px" - section: unknown tag: div height: 96px width: 1048px layout: block children: 1 - section: content-section tag: div classes: ["framer-17mbdsy-container"] height: 412px width: 713px layout: block children: 1 - section: unknown tag: div classes: ["framer-o9bfvf-container"] height: 96px width: 1048px layout: block children: 1 - section: feature-section tag: div height: 868px width: 1200px layout: flex-column justify=center children: 1 padding: "0px 12px" - section: unknown tag: div height: 96px width: 1048px layout: block children: 1 - section: unknown tag: div height: 300px width: 300px layout: block children: 1 - section: unknown tag: div classes: ["framer-12pddbm-container"] height: 200px width: 315px layout: block children: 1 - section: logo-strip tag: div height: 199px width: 333px layout: block children: 1 - section: unknown tag: div height: 96px width: 1048px layout: block children: 1 - section: feature-section tag: div height: 1238px width: 1200px layout: flex-column justify=center children: 1 padding: "0px 12px" - section: unknown tag: div height: 96px width: 1048px layout: block children: 1 - section: unknown tag: div height: 412px width: 470px layout: block children: 1 - section: unknown tag: div height: 412px width: 383px layout: block children: 1 - section: content-section tag: div height: 435px width: 680px layout: block children: 1 - section: unknown tag: div height: 96px width: 1048px layout: block children: 1 - section: feature-section tag: div height: 569px width: 1200px layout: flex-column justify=center children: 1 padding: "0px 12px" - section: unknown tag: div classes: ["framer-1srnfz-container"] height: 96px width: 1048px layout: block children: 1 - section: testimonials tag: div classes: ["framer-mxjprm-container"] height: 691px width: 1200px layout: block children: 1 - section: unknown tag: div height: 96px width: 1048px layout: block children: 1 - section: content-section tag: section height: 298px width: 524px layout: flex-row justify=normal children: 2 - section: content-section tag: div classes: ["framer-16usawc-container"] height: 298px width: 524px layout: block children: 1 - section: unknown tag: div height: 298px width: 524px layout: block children: 1 vertical-padding: ~24px - section: unknown tag: div classes: ["framer-13kxqne-container"] height: 298px width: 524px layout: block children: 1 vertical-padding: ~24px ``` **Agent rule**: rebuild sections in this order (sorted by vertical position). Match the layout primitive (grid N-col / flex direction / block). ## 14. Copy Library (Real Content from Source) *Actual text content extracted from the live page. Use these strings verbatim when reproducing the site — they carry the brand voice.* ```yaml copy: section-headings: - "With us, appointment scheduling is easy" - "Cal.com" - "All your key tools in-sync with your meetings" sub-headings: - "Connect your calendar" - "Meeting is starting now" - "Accept payments" - "Built-in video conferencing" ``` **Agent rule**: reuse these exact strings when generating UI. Do NOT translate or rephrase — brand voice is preserved through the original wording. ## 15. Asset Inventory (Image Roles & Ratios) *Image inventory classified by role and aspect ratio. When reproducing the site, allocate this number of assets per role.* ```yaml assets: thumbnail: count: 48 avg-ratio: 1.00 common-aspect: "~1:1 square" ``` **Agent rule**: when generating placeholder images, match these counts and aspect ratios. Use neutral placeholder backgrounds for `product` (e.g. `#f5f5f5`), full-color photography hints for `hero` and `editorial`. ## 17. Content Architecture & Resources (Links by Purpose) *The page's links classified by purpose — the information architecture to reproduce. Categories, featured images, devices and projects are extracted from the rendered DOM, not guessed.* **By purpose:** **cta** 3 · **auth** 1 · **product** 2 · **pricing** 1 · **docs** 6 · **blog** 2 · **social** 2 · **footer** 36 · **other** 7 **Primary actions (conversion path):** - Primary call-to-action — "Get started" (the conversion path) → `https://app.cal.com/signup` - Primary call-to-action — "Sign up with Google" (the conversion path) → `https://app.cal.com/auth/sso/google` - Primary call-to-action — "Sign up with email" (the conversion path) → `https://app.cal.com/signup` - Account access — "Sign in" (login/signup) → `https://app.cal.com/auth/login?_gl=1*1d3xgrt*_gcl_au*MTY1ODY5NjUwMS4xNzQxOTczMzA5*_ga*MTA0ODE0ODU4LjE3NDE5NzMzMTA.*_ga_RX4HHQ613S*MTc0MTk3MzMwOS4xLjEuMTc0MTk3MzY2NC42MC4wLjk4NDg1NDg4` **Signals:** 19/60 links carry a featured image · device mockups detected: tablet ×5 · dominant link roles: footer-link (46), inline-link (6), content-card (4). --- ## Extraction Completeness: 65/100 (C) | Category | Score | Max | Detail | |----------|-------|-----|--------| | Colors & Palette | 25 | 25 | 21 named colors | | Typography | 13 | 20 | 5 roles defined | | Components | 4 | 20 | 1 specs extracted | | Motion & Interaction | 10 | 15 | Keyframes | | CSS Custom Properties | 4 | 10 | 77 vars | | Responsive Breakpoints | 5 | 5 | 5 breakpoints | | Variable Fonts | 5 | 5 | GEOM, WGHT axes | ## 12. Known Gaps & Confidence Explicit list of what this extraction could NOT capture. Agents should not invent values for these — either skip the feature or use the documented baseline + heuristic fallback. *Auto-detected extraction limitations — understand before building:* - **Sparse component extraction** — fewer than 5 component types detected. Highly dynamic sections (modals, datepickers, carousels) require interaction to render and are not captured in a static pass. | Category | What's missing | Fallback strategy | |----------|----------------|-------------------| | **Hero imagery** | No dominant hero image detected above the fold | Use the canonical brand visual from §9b (OG image) for hero composition | | **Dark mode** | No dark-mode CSS variables or media queries detected | Light mode is canonical; do not generate dark-mode variants unless explicitly requested | | **Form inputs** | No text input fields detected on this page | Use the documented border-radius + accent border on focus; 12-16px padding inside | ### Per-section confidence | Section | Confidence | Reason | |---------|------------|--------| | §1 Visual Theme | High | Body bg extracted via getComputedStyle() | | §2 Colors | High | 77 CSS vars (semantic naming requires ≥20 for high) | | §3 Typography | High | 5 typography roles inferred | | §4 Components | Low | 1 component variants captured | | §7 Motion | High | Keyframes + transitions | | §8 Do's/Don'ts | High | 14 rules generated; design-decisions.json has evidence per rule | | §9 Responsive | High | 5 breakpoints detected | | §9b Photography | Medium | 3 images, hero not detected | ## 11.1 CSS Implementation Guide (CSS Interception Engine v2.15+) *Ready-to-use CSS from Prism's CSS Interception Engine — intercepted directly from the site's CSS files (bypasses CORS).
