## 0. Quick Reference
**Stack:** Next.js · CSS Modules (Sass) · Custom font system · Token source: reconstructed-from-computed (low confidence, 1 CSS custom property found)
**How to apply:** Use as `var(--cash-*)` in CSS, `style={{ prop: 'var(--cash-*)' }}` in JSX, or `bg-[var(--cash-*)]` in Tailwind.
```css
:root {
/* BRAND */
--cash-green: rgb(0, 224, 19); /* Cash App signature green — CTAs, brand accents */
--cash-black: rgb(0, 0, 0); /* Primary text, nav background */
--cash-white: rgb(255, 255, 255); /* Button fill on dark bg, body text on dark surface */
/* TYPOGRAPHY — composite (Cash Sans is the ONLY permitted font) */
--cash-font-stack: "Cash Sans", "Helvetica Neue", helvetica, sans-serif;
--cash-font-stack-wide: "Cash Sans Wide", "Helvetica Neue", helvetica, sans-serif;
--cash-font-stack-mono: "Cash Sans Mono", monospace;
/* TYPE SCALE */
--cash-font-size-xs: 12px;
--cash-font-size-sm: 14px;
--cash-font-size-md: 16px; /* body — rounds 15.9999px */
--cash-font-size-lg: 18px; /* large body / subheads */
--cash-font-size-xl: 24px; /* section labels */
--cash-font-size-2xl: 40px; /* h2/h3 */
--cash-font-size-3xl: 56px; /* h1 hero */
/* SPACING */
--cash-space-xs: 8px; /* tight gaps (rounded from 10.5px) */
--cash-space-sm: 16px; /* standard inline padding */
--cash-space-md: 20px; /* card gap, section rhythm */
--cash-space-lg: 24px; /* component breathing room */
--cash-space-xl: 32px; /* section inner padding */

--cash-space-3xl: 96px; /* hero/footer spacing */
/* RADIUS */

--cash-radius-pill: 100px; /* primary buttons — pill shaped */
/* MOTION */
--cash-duration-fast: 0.3s;
--cash-ease-default: ease;
}
```
```tsx
// Primary pill button — correct token usage
<button style={{
fontFamily: 'var(--cash-font-stack)',
fontSize: 'var(--cash-font-size-sm)',
backgroundColor: 'var(--cash-white)',
color: 'var(--cash-black)',
borderRadius: 'var(--cash-radius-pill)',
padding: '14px var(--cash-space-sm)',
transition: `opacity var(--cash-duration-fast) var(--cash-ease-default)`,
border: 'none', cursor: 'pointer',
}}>Get started</button>
```
**NEVER rules:**
- NEVER use Inter, Roboto, Arial, or any font other than Cash Sans / Cash Sans Wide / Cash Sans Mono
- NEVER use a button border-radius other than `100px` (pill) for primary CTAs
- NEVER hardcode `#00e013` or `rgb(0,224,19)` — always use `var(--cash-green)`
- NEVER use spacing values outside the `--cash-space-*` scale
- NEVER omit hover state opacity (`0.7`) on interactive elements — it is the universal hover pattern
- NEVER use `!important` to override token values
- NEVER construct dynamic Tailwind class strings like `` `bg-[${color}]` `` — values won't be tree-shaken

## 1. Design Direction & Philosophy
### Character & Mood
Cash App presents a **bold, minimal, high-contrast** aesthetic rooted in financial confidence. The design is dark-first (black backgrounds, white text) with a single electric accent — **Cash App Green (`rgb(0, 224, 19)`)** — used sparingly for brand recognition and CTAs. The visual language is clean and assertive: large typographic headlines at low font-weight (400), generous whitespace, and pill-shaped CTAs.
### What This Design IS
- **Dark-field dominant:** The page background is black. Content appears on black. White and green are accent.
- **Typography-forward:** Headlines run at `56px` weight `400` — the type carries the visual hierarchy, not decoration.
- **Radically simple interaction model:** Hover = `opacity: 0.7` or `opacity: 0.8`. No complex transform choreography except on image cards (scale 1.05).
- **Brand-owned typeface:** Cash Sans (Regular 400, Medium 500, Semibold 600, Bold 700, Black 900) + Cash Sans Wide + Cash Sans Mono. This typeface is the primary brand differentiator.
### What This Design Explicitly REJECTS
- Warm colour palettes, gradients, or decorative illustration styles
- Rounded corners on non-button elements (cards have `0px` radius)
- Serif or geometric sans fonts (no Inter, Roboto, Helvetica as primary)
- Heavy drop shadows or layered elevation effects on content cards
- Busy layouts — whitespace is structural, not incidental

## 2. Colour System
### Tier 1 — Primitive Values
```css
:root {
/* Primitive palette */
--cash-primitive-green: rgb(0, 224, 19); /* Cash App Green — brand signature */
--cash-primitive-black: rgb(0, 0, 0); /* Pure black */
--cash-primitive-white: rgb(255, 255, 255); /* Pure white */
--cash-primitive-gray-100: rgb(244, 244, 244); /* Lightest gray — nav item hover bg */
--cash-primitive-gray-200: rgb(240, 240, 240); /* Light gray — pill/tag hover */
--cash-primitive-gray-300: rgb(229, 229, 229); /* Medium-light — dropdown item hover */
--cash-primitive-gray-400: rgb(184, 184, 184); /* Medium — scrollbar thumb hover */
--cash-primitive-gray-500: rgb(153, 153, 153); /* Disabled locale option text */
--cash-primitive-gray-600: rgb(115, 115, 115); /* Article tag border hover */
--cash-primitive-gray-700: rgb(102, 102, 102); /* Footer link hover */
--cash-primitive-gray-800: rgb(75, 75, 75); /* Disabled menu item text */
--cash-primitive-purple: rgb(84, 32, 194); /* Presale secondary hover */
--cash-primitive-link-blue: rgb(0, 0, 238); /* Default browser link — avoid using */
}
```
### Tier 2 — Semantic Aliases
```css
:root {
/* Surface */
--cash-bg-surface: var(--cash-primitive-green); /* Page brand surface / CTA background */
/* reconstructed: medium confidence — from --brand-surface-1 on 2 elements */

--cash-color-surface-nav: var(--cash-primitive-black); /* Navigation bar background */
--cash-color-surface-elevated: var(--cash-primitive-white); /* Cards on dark bg, modal surfaces */
/* Text */
--cash-color-text-primary: var(--cash-primitive-white); /* Body text on dark backgrounds */
--cash-color-text-inverted: var(--cash-primitive-black); /* Text on white/green surfaces */
--cash-color-text-heading: var(--cash-primitive-black); /* h1–h3 (these render on white sections) */
--cash-color-text-muted: var(--cash-primitive-gray-700); /* Secondary/footer text */
--cash-color-text-disabled: var(--cash-primitive-gray-500); /* Disabled state text */
/* Interactive */
--cash-color-action-primary-bg: var(--cash-primitive-white); /* Primary button bg (on dark surfaces) */
--cash-color-action-primary-text: var(--cash-primitive-black); /* Primary button label */
--cash-color-action-brand: var(--cash-primitive-green); /* Brand CTA, sign-up */
--cash-color-hover-overlay: 0.7; /* Opacity value for hover states */
/* Borders */
--cash-color-border-input: rgb(112, 112, 112); /* Input field border */
--cash-color-border-tag: var(--cash-primitive-gray-600); /* Article tag border hover */
/* Focus */
--cash-color-focus-ring: var(--cash-primitive-black); /* Focus outline — 2px solid */
}
```
### Tier 3 — Component Tokens
```css
:root {
/* Button */
--cash-btn-primary-bg: var(--cash-color-action-primary-bg);
--cash-btn-primary-text: var(--cash-color-action-primary-text);
--cash-btn-brand-bg: var(--cash-color-action-brand);
--cash-btn-brand-text: var(--cash-primitive-black);
/* Nav */
--cash-nav-bg: var(--cash-color-surface-nav);
--cash-nav-text: var(--cash-primitive-white);
/* Input */
--cash-input-bg: var(--cash-primitive-white);
--cash-input-border: var(--cash-color-border-input);
--cash-input-text: var(--cash-primitive-black);
--cash-input-radius: 50px; /* pill-shaped input */
/* Card */
--cash-card-bg: transparent;
--cash-card-text: var(--cash-primitive-black);
--cash-card-radius: 0px; /* cards have NO border-radius in base design */
}
```
### Colour Usage Table
| Token | Value | Usage |
|---|---|---|
| `--cash-green` | `rgb(0, 224, 19)` | **Brand signature** — CTAs, brand moments |
| `--cash-black` | `rgb(0, 0, 0)` | Page bg, nav bg, heading text |
| `--cash-white` | `rgb(255, 255, 255)` | Button fill, body text on dark |
| `--cash-primitive-gray-300` | `rgb(229, 229, 229)` | Dropdown hover states |
| `--cash-primitive-purple` | `rgb(84, 32, 194)` | Presale secondary only |

### Type Scale Table
| Role | Size | Weight | Line Height | Letter Spacing |
|---|---|---|---|---|
| Hero H1 | `56px` | `400` | `53.2px` | `-1.68px` |
| Section H2/H3 | `40px` | `400` | `44px` | `-1.2px` |
| Card H4 | `24px` | `400` | `normal` | — |
| Body Large | `18px` | `400` | `25.2px` | — |
| Body | `16px` | `400` | `19.2px` | — |
| Button | `14px` | `400` | `14px` | `-0.28px` |
| Caption/XS | `12px` | `500` | `normal` | — |
**Key rule:** Headings use weight `400` — NOT bold. Cash App's hierarchy comes from **size**, not weight.
### Pairing Rules
- **Cash Sans** — all UI text, body copy, navigation, buttons
- **Cash Sans Wide** — display/hero moments only, never body text
- **Cash Sans Mono** — financial amounts, account numbers, codes only
- NEVER mix with system fonts except as declared fallbacks

## 4. Spacing & Layout
```css
:root {
/* ── BASE UNIT: 8px grid ── */
/* Note: source has off-grid values (10.5px, 15.99px, 19.88px).
These are normalised to the nearest 4px multiple for the token system.
The original computed values are preserved in component documentation. */
--cash-space-1: 4px; /* micro — icon gaps, border offsets */
--cash-space-2: 8px; /* tight — inline element spacing, gap in buttons */
--cash-space-3: 12px; /* small — compact padding */
--cash-space-4: 16px; /* base — standard padding, sm spacing */
--cash-space-5: 20px; /* medium — card grid gap (matches cls_card gap:20px) */
--cash-space-6: 24px; /* large — component breathing room */
--cash-space-8: 32px; /* xl — section inner padding */
--cash-space-12: 48px; /* 2xl — between components */
--cash-space-16: 64px; /* section vertical rhythm */
--cash-space-24: 96px; /* hero-scale — footer spacing */

/* ── FOOTER SPACING ── */
--ot-footer-space: 160px; /* extracted: high confidence — preserved original name */
/* ── BUTTON PADDING (exact computed values) ── */
--cash-btn-padding-v: 14px; /* vertical — exact from computed */
--cash-btn-padding-h: var(--cash-space-sm); /* horizontal ≈ 16px (source: 19.88px) */

--cash-radius-image: 14.3%; /* responsive images, footer text cards — extracted: high confidence */
/* Note: 15.9%/13% (elliptical) appears on video/image containers — reconstructed: moderate confidence */
/* ── NAVIGATION ── */

}
```
### Breakpoint Scale
| Name | Value | Notes |
|---|---|---|
| `xs` | `391px` | Small phones |
| `sm` | `500px` | Mid-range mobile |
| `md` | `760px` | Tablet portrait |
| `lg` | `1024px` | Desktop baseline |
| `xl` | `1400px` | Wide desktop |
| `2xl` | `1680px` | Ultra-wide |
Key pairs: `759px`/`760px` and `1023px`/`1024px` are mobile/desktop breakpoints (below/above logic).

## 5. Page Structure & Layout Patterns
> Token source is layout digest only — no screenshots provided. All section rows marked **"(inferred)"** are derived from component inventory + computed styles. Rows marked **"(extracted)"** are anchored to digest values.
### 5.1 Section Map
| # | Section | Layout Type | Key Elements | Source |
|---|---|---|---|---|
| 1 | Nav/Header | Flex column, centered | Logo, nav links, Sign up CTA (green), Log in | extracted |
| 2 | Hero | Full-width, block | H1 at 56px/400, arrow `→` glyph at 56px, body copy | inferred |
| 3 | Feature/Card Grid | CSS Grid, gap 20px | Stat cards (h4 + body), imagery with 14.3% radius | extracted |
| 4 | Product Features | Alternating block | H2 + body large + pill CTA, app imagery | inferred |
| 5 | App Store Badges | Flex row | "Editor's Choice", "9.9m+ Apple App Store", "4.5★" cards | extracted |
| 6 | FAQ / Accordion | Block, full-width | H3 question rows, expand/collapse, opacity hover | inferred |
| 7 | Press / Archive | Flex row, pill filters | Year pill filters, press logos | inferred |
| 8 | Footer | Flex column/row | Links, locale switcher, legal text | inferred |
### 5.2 Layout Patterns
**Navigation** (extracted from `role_navigation` computed styles):
```
display: flex
flex-direction: column
justify-content: center
align-items: center
padding-top: 86px /* --cash-nav-padding-top */
background: rgb(0,0,0) /* --cash-black */
```
**Card Grid** (extracted from `cls_card` computed styles):
```
display: grid
gap: 20px /* --cash-space-5 */
/* column count: [TBD - extract manually] — likely 2–3 col at desktop */
```
**Primary Button** (extracted from `button_primary` computed styles):
```
display: flex
flex-direction: row
justify-content: center
align-items: center
gap: 10.5px /* use --cash-btn-gap (8px normalised) */
padding: 14px 19.88px /* use --cash-btn-padding-v / -h */
border-radius: 100px /* --cash-radius-pill */
background: rgb(255,255,255) on dark bg; rgb(0,224,19) for brand CTA
```
**Image/Video Containers:**
- Responsive images: `border-radius: 14.3%` (aspect-ratio-relative, creates organic rounding)
- Background video containers: `border-radius: 15.9% / 13%` (elliptical)
- Cards: `border-radius: 0px` — sharp corners
### 5.3 Visual Hierarchy
- **H1 at 56px/400 weight** is the dominant visual element in the hero — size alone creates hierarchy
- **Cash App Green** (`rgb(0, 224, 19)`) appears on the primary sign-up CTA ("Sign up now→") and brand surface moments only — it is the single most visually distinct element
- **Arrow glyph `→`** rendered at `56px` creates a kinetic call-to-action alongside the hero headline
- White pill buttons on black backgrounds are the secondary CTA pattern
- App store social proof cards (Editor's Choice, ratings) use `14.3%` border-radius, appearing as "squircle" frames
- Hover universally = `opacity: 0.7` (buttons) or `opacity: 0.8` (cards, links, media)
### 5.4 Content Patterns
**Stat/Badge Card** (repeating):
```
[Squircle-framed image or icon]
[H4 — feature label]
[Body copy — 16–18px, 400 weight]
[Optional: pill CTA]
```
**Feature Row** (alternating, inferred):
```
[H2 at 40px] + [Body Large at 18px] — left column
[App screenshot or video] — right column
Alternates L/R on subsequent sections
```
**FAQ Item** (extracted from hover states):
```
[H3 question — opacity 0.7 on hover]
[Body answer — revealed on expand]
```

## 6. Component Patterns
### 6.1 Primary Button
**Anatomy:** `<button>` → `[optional icon]` + `[label text]`
**Token mappings:**
| State | background | color | opacity | border-radius |
|---|---|---|---|---|
| Default | `--cash-white` | `--cash-black` | `1` | `--cash-radius-pill` |
| Hover | `--cash-white` | `--cash-black` | `0.7` | `--cash-radius-pill` |
| Focus | `--cash-white` | `--cash-black` | `1` | `--cash-radius-pill` |
| Active | `--cash-white` | `--cash-black` | `0.85` | `--cash-radius-pill` |
| Disabled | `--cash-white` | `--cash-black` | `0.3` | `--cash-radius-pill` |
| Brand/CTA | `--cash-green` | `--cash-black` | `1` | `--cash-radius-pill` |
```tsx
import { ButtonHTMLAttributes, ReactNode } from 'react';

justifyContent: 'center',
gap: 'var(--cash-space-2)', /* 8px */
transition: `opacity var(--cash-duration-fast) var(--cash-ease-default)`,

## 7. Elevation & Depth
```css
:root {
/* ── SHADOWS ── */
/* Base design: NO shadows on most elements (boxShadow: none across card, button, nav, modal) */
--cash-shadow-none: none;
/* Store tile hover — only shadow found in extraction */
--cash-shadow-card-hover: rgba(0, 0, 0, 0.12) 0px 8px 24px;
/* extracted: high confidence — from .store-tile:hover computed state */
/* Scrollbar thumb hover (internal) */
--cash-shadow-scrollbar: rgb(184, 184, 184); /* bg-color only, no box-shadow */
/* ── Z-INDEX SCALE ── */
--cash-z-base: 0; /* page content */
--cash-z-card: 1; /* elevated cards */
--cash-z-nav: 100; /* navigation bar */
--cash-z-modal: 200; /* modal overlays */
--cash-z-toast: 300; /* transient alerts */
/* reconstructed: moderate confidence — no explicit z-index values extracted */
/* ── BORDERS ── */
--cash-border-input: 1px solid rgb(112, 112, 112); /* Input fields */
--cash-border-tag: 1px solid var(--cash-primitive-gray-600); /* Article tags on hover */
--cash-border-focus: 2px solid rgb(0, 0, 0); /* Focus ring — extracted from modal close button */
}
```
### Layering Principles
- **Default state:** No shadows. Cash App uses **opacity reduction** as the depth/de-emphasis tool, not shadows.
- **Card hover only:** `rgba(0,0,0,0.12) 0px 8px 24px` — used for store tile lift effect with `translateY(-2px)`
- **Modals:** Use `fadein` keyframe animation (opacity 0→1), not drop shadows for emphasis
- NEVER add box shadows to buttons — the design uses opacity not elevation for button feedback
---
## 8. Motion
```css
:root {
/* ── DURATION ── */
--cash-duration-fast: 0.3s; /* universal transition — extracted: high confidence */
/* All interactive elements use 0.3s. No slow (0.5s+) transitions found. */
/* ── EASING ── */
--cash-ease-default: ease; /* universal easing — extracted: high confidence */
/* ── TRANSITION SHORTHAND ── */
--cash-transition-default: all var(--cash-duration-fast) var(--cash-ease-default);
--cash-transition-opacity: opacity var(--cash-duration-fast) var(--cash-ease-default);
--cash-transition-transform: transform var(--cash-duration-fast) var(--cash-ease-default);
}
/* ── KEYFRAMES ── */
/* Fade in — used for modals and image lazy-load */
@keyframes cash-fadein {
0% { opacity: 0; }
100% { opacity: 1; }
}
/* Intro animation — used for feature/splash screens */
@keyframes cash-introAnimation {
0% { opacity: 0; transform: scale(1.05); }
100% { opacity: 1; transform: scale(1); }
}
/* Pulse — used for campaign form elements */
@keyframes cash-pulse {
0% { opacity: 1; transform: scale(0.4); }
100% { opacity: 0.1; transform: scale(1.1); }
}
/* Floating CTA slide-in (mobile) */
@keyframes cash-ctaSlideIn {
100% { width: 90vw; left: 5vw; transform: translateY(0px); }
}
/* Floating CTA slide-out (mobile) */
@keyframes cash-ctaSlideOut {
100% { width: 90vw; left: 5vw; transform: translateY(calc(100% + 20px)); }
}
```
### Motion Rules
- **ANIMATE:** opacity changes on hover (0.3s ease), modal entrance (fadein), image lazy-load (fadein), image card hover scale (0.3s ease), floating CTA enter/exit
- **DO NOT ANIMATE:** layout shifts, font changes, colour swaps (use instant transitions for these)
- **Hover pattern is uniform:** `opacity: 0.7` for interactive text/buttons, `opacity: 0.8` for cards and media links
- Respect `prefers-reduced-motion` — wrap non-essential keyframe animations in `@media (prefers-reduced-motion: no-preference)`

## 9. Anti-Patterns & Constraints
1. **NEVER use Inter, Roboto, Arial, or any web-safe font as primary.**
→ Why it fails: AI coding agents default to `font-family: 'Inter', sans-serif` or `font-family: system-ui` when no font context is provided. This completely erases the Cash Sans brand identity — the typeface is the #1 visual differentiator.
→ What to do instead: Always declare `font-family: 'Cash Sans', 'Helvetica Neue', helvetica, sans-serif` on the root element. Load fonts from the CDN paths in Section 3.
2. **NEVER use hardcoded hex or rgb values for the brand green (`#00e013`, `rgb(0,224,19)`).**
→ Why it fails: If the brand green is hardcoded, a single brand update requires a global search-and-replace across hundreds of files. Agents also tend to use nearby approximations like `#00ff00` or `lime` which are perceptually wrong.
→ What to do instead: Use `var(--cash-green)` exclusively. Define the token once in `:root`.
3. **NEVER apply border-radius other than `100px` to primary CTA buttons.**
→ Why it fails: Agents trained on generic design systems default to `border-radius: 8px` or `border-radius: 0.375rem`. Cash App uses fully pill-shaped buttons (`100px`). Using 8px creates a fundamentally different visual language.
→ What to do instead: Apply `border-radius: var(--cash-radius-pill)` (`100px`) to all primary and brand buttons. Use `0px` for cards and sections.
4. **NEVER use spacing values outside the `--cash-space-*` token scale.**
→ Why it fails: 4 off-grid values were found in extraction (10.5px, 15.99px, 19.88px, 90px). Agents that copy these exact computed values will perpetuate broken rhythm. Meanwhile agents that invent arbitrary values like `margin: 13px` introduce new inconsistencies.
→ What to do instead: Round to the nearest 4px multiple and use the corresponding `--cash-space-*` token. Document the original computed value in a comment if exact fidelity is needed for a specific component.
5. **NEVER add box-shadow to buttons or standard cards.**
→ Why it fails: Agents trained on Material Design or Bootstrap patterns auto-apply `box-shadow: 0 2px 4px rgba(0,0,0,0.2)` to buttons. Cash App's depth language is opacity-based, not shadow-based. Shadows appear ONLY on store tile hover.
→ What to do instead: Use `opacity: 0.7` on hover (buttons) or `opacity: 0.8` (card links). Reserve `--cash-shadow-card-hover` exclusively for store tile hover with the matching `translateY(-2px)` transform.
6. **NEVER construct dynamic Tailwind class strings.**
→ Why it fails: Tailwind's JIT compiler only includes classes present as complete strings at build time. Writing `` `bg-[${brandColor}]` `` causes the class to be tree-shaken and the style never applies — the element renders unstyled.
→ What to do instead: Use `style={{ backgroundColor: 'var(--cash-green)' }}` for dynamic values, or define complete static class strings in a variant map.
7. **NEVER omit hover, focus, and disabled states on interactive elements.**
→ Why it fails: Agents frequently generate only the default state. Cash App uses a universal but specific pattern: hover = `opacity: 0.7` for buttons, `opacity: 0.8` for card links. Without these, the UI feels broken — users get no affordance feedback.
→ What to do instead: Every `<button>`, `<a>`, and interactive `<div>` must handle: default → hover (opacity change) → focus (2px solid black outline, 2px offset) → disabled (opacity 0.3, cursor not-allowed). See component patterns in Section 6.
8. **NEVER use `font-weight: 700` or `bold` on headings.**
→ Why it fails: H1 through H3 are all `font-weight: 400` on cash.app. Agents defaulting to bold headings create a visual hierarchy that contradicts the brand — Cash App uses SIZE (56px/40px) not weight to establish heading hierarchy.
→ What to do instead: Set headings to `font-weight: 400`. Use `font-weight: 600` only for `<label>` elements and semibold UI text. Reserve 700+ for maximum emphasis only.
9. **NEVER use `position: absolute` to achieve layout alignment in nav or card grids.**
→ Why it fails: Absolute positioning breaks reflow — nav items and card grids collapse or overlap at breakpoints. The extraction confirms nav uses `display: flex; flex-direction: column` and card grids use `display: grid; gap: 20px`.
→ What to do instead: Use flexbox for navigation and single-axis alignment. Use CSS grid with `gap: var(--cash-space-5)` for card grids. Only use absolute positioning for genuinely overlapping elements (floating CTAs, tooltips, overlays).
10. **NEVER use `!important` to override design tokens.**
→ Why it fails: `!important` bypasses the token cascade entirely. When a brand update changes `--cash-green`, components with `!important` rules will not inherit the update — causing visual drift that's hard to debug.
→ What to do instead: Fix specificity at the selector level. If a third-party library (e.g., bootstrap, OneTrust) overrides your styles, increase selector specificity with a parent class, or use CSS Layers (`@layer`) to establish the correct cascade order.
11. **NEVER use placeholder text or `Lorem ipsum` in component examples.**
→ Why it fails: AI agents copy example content into production when refactoring. "Lorem ipsum" in a financial product creates trust issues and accessibility failures (screen readers announce it as content).
→ What to do instead: Use real Cash App content strings ("The way money should work", "Get started", "Send money for free") from the extracted element inventory.

## Appendix B: Token Source Metadata
```yaml
tokenSource: reconstructed-from-computed
site: cash.app
extractedAt: 2024
cssCustomPropertiesFound: 1
# Only --ot-footer-space (OneTrust third-party) and --brand-surface-1 (green) were found as actual CSS custom properties.
# All other tokens are synthesised from computed styles on key elements.
confidence: low
# Low confidence due to minimal CSS custom property usage. Cash App uses CSS Modules
# (Sass), meaning design tokens are compiled away at build time and not exposed as
# runtime CSS variables. The reconstructed token system represents the computed
# output, not necessarily the source Sass variables.
clusteringMethod:
colours: "Grouped by hue family (black cluster, white/gray cluster, green accent).
Gray scale clustered by usage context (hover states, disabled states, borders).
Only 2 truly distinct brand colours: black and Cash App Green."
spacing: "Clustered around 4px grid. Source values 10.5px, 15.99px, 19.88px, 90px
are off-grid — rounded to 8px, 16px, 20px, 96px respectively.
Exact source values preserved in component-level documentation."
radius: "Four distinct values extracted from page elements.
2px (small chrome), 50px/100px (pill forms/buttons), 14.3% (squircle images),
15.9%/13% (elliptical containers).
WARNING: 14.3% and 15.9%/13% are percentage-based (aspect-ratio-relative),
not fixed pixel values — must be applied to elements where aspect ratio is known."
typography: "High confidence. 5 discrete font sizes form a clear scale (12/14/16/18/24/40/56px).
Font family is uniquely identifiable (Cash Sans CDN paths extracted).
Letter-spacing values extracted directly from computed h1/h2/button styles."
motion: "High confidence. Single duration (0.3s) and single easing (ease) dominate all 185+
transition-bearing elements. Keyframe animations extracted from CSS rule names."
notes:
- "Cash Sans is a proprietary typeface served from cash-f.squarecdn.com CDN.
Do not substitute with any system or Google font."
- "The body element has color: rgb(255,255,255) — the page default is WHITE TEXT on BLACK bg.
Heading elements (h1-h3) show color: rgb(0,0,0) indicating section-level background inversions."
- "Modal element uses Arial as font-family — this appears to be a third-party overlay
(OneTrust cookie banner), NOT the Cash App design system. Do not replicate."
- "bootstrap detected as a library dependency — may contribute some utility classes,
but Cash App styles override via CSS Modules specificity."
- "nextJs detected — CSS Modules (Sass) is the styling approach, confirmed by
hashed classnames in extracted selectors (e.g. __6sJe3W__button, __yuR0Wa__responsiveImage)."
- "radius-md (14.3%) and radius-lg (15.9%/13%) are used on images and media containers,
NOT on UI chrome or buttons. Their percentage-based values create a consistent
'squircle' effect tied to the element's own dimensions."
