## 1. Design Direction & Philosophy

### Character & Aesthetic Intent
Pinterest's visual language is **clean, content-first, and quietly systematic**. The UI deliberately recedes so that user-generated imagery — pins, boards, and collections — can dominate the viewport. Chrome is reduced to the minimum; surfaces are off-white rather than stark white, gradients are used only to darken imagery overlays, and the singular brand moment is the **Pinterest red (`#e60023`)** on CTA buttons and the logo.

The typographic voice is confident but not loud. The custom typeface "Pin Sans" is used exclusively throughout — it is the only brand typeface. Display sizes (60–72px) carry strong letterspacing compression (`-1px`) to create density at large scale. Body copy sits at 14px with `font-weight: 700` — heavier than convention, reflecting the bold editorial feel.

### What This Design Explicitly Rejects
- **No decorative illustration or heavy iconography** in structural UI — icons are utility-only
- **No warm or vibrant surface colours** — backgrounds stay in the warm-neutral grayscale family (`#fbfbf9` to `#fff`)
- **No rounded corners above 16px on standard UI** — pill shape (`999px`) is reserved for search chips and specific link badges only; it is not the default button shape
- **No gradient backgrounds on surfaces** — gradients are reserved for image overlays (`linear-gradient(180deg, transparent, rgba(0,0,0,.8))`)
- **No sharp (0px) corners on interactive controls** — all buttons and inputs use at minimum `--pintrest-radius-lg` (16px)
- **No system font fallbacks as first-choice** — "Pin Sans" must always lead the font stack

## 4. Spacing & Layout

### Spacing Scale

```css
/* ── Base: approximate 4px grid, with 10px and 14px as brand-specific values ── */
/* Note: 10px and 14px are intentional off-grid values in Pinterest's system */

--pintrest-space-sm: 10px;   /* original: --sema-space-250 — tight internal padding */
--pintrest-space-md: 14px;   /* original: --sema-space-350 — button vertical padding (6px) + context */
--pintrest-space-lg: 16px;   /* original: --sema-space-400 — nav padding, standard internal gap */
--pintrest-space-xl: 24px;   /* original: --sema-space-600 — section internal spacing */
--pintrest-space-2xl: 32px;  /* original: --sema-space-800 — section separation */
--pintrest-space-3xl: 48px;  /* original: --sema-space-1200 — large section gaps */

/* Note: --pintrest-space-xs maps to --sema-space-1600 (64px) which is a blur value,
   not a spacing value. Treat 64px as an XL blur token, not layout spacing. */
```

### Semantic Space Tokens (from extracted system)

```css
--sema-space-0: 0px;         /* Zero — focus outline offsets */
--sema-space-50: 2px;        /* Micro — focus ring gap */
--sema-space-100: 4px;       /* XS — icon internal padding */
--sema-space-200: 8px;       /* SM — compact padding */
--sema-space-250: 10px;      /* SM+ — tight component padding */
--sema-space-300: 12px;      /* MD- — card internal */
--sema-space-350: 14px;      /* MD — button padding */
--sema-space-400: 16px;      /* MD+ — standard nav/section padding */
--sema-space-600: 24px;      /* LG — section internal */
--sema-space-800: 32px;      /* XL — between components */
--sema-space-1200: 48px;     /* 2XL — section gap */
```

### Button & Input Padding (from computed styles)

```css
/* Button primary: padding 6px 14px */
/* Input: padding 11px 15px */
/* Navigation: padding 16px */
```

### Grid System & Breakpoints

```css
/* ── Responsive Breakpoints ── */
/* extracted: high confidence */
@custom-media --bp-sm (min-width: 576px);    /* Small — compact mobile → standard mobile */
@custom-media --bp-md (min-width: 768px);    /* Medium — tablet portrait */
@custom-media --bp-lg (min-width: 890px);    /* Large — tablet landscape / small desktop */
@custom-media --bp-xl (min-width: 1312px);   /* XL — standard desktop */
@custom-media --bp-2xl (min-width: 1440px);  /* 2XL — wide desktop */
@custom-media --bp-3xl (min-width: 1680px);  /* 3XL — ultrawide */
@custom-media --bp-4xl (min-width: 2048px);  /* 4XL — retina/4K displays */
```

### Layout Rules
- **Navigation:** `display: flex; flex-direction: row; justify-content: space-between; align-items: center; padding: 16px;` — full-width, white background
- **Modal/Sheet:** `display: flex; flex-direction: row; justify-content: center; align-items: center;` — centred overlay
- **Masonry grid (pin feed):** Multi-column masonry using CSS columns or JS masonry — column count responsive across breakpoints
- **Container:** Not a fixed max-width container — Pinterest uses edge-to-edge layouts at all breakpoints, with internal component padding providing breathing room

## 5. Page Structure & Layout Patterns

> **Note:** No screenshots provided. Section derived from LAYOUT DIGEST, computed styles, and component inventory. Rows marked **(inferred)** are probable but not visually confirmed.

### 5.1 Section Map

| # | Section | Layout Type | Approx. Height | Key Elements | Confidence |
|---|---|---|---|---|---|
| 1 | **Top Navigation** | Flex row, full-width | ~64px | Logo (Pinterest wordmark), Search bar, Nav links, Log in / Sign up buttons | extracted |
| 2 | **Hero / Signup Panel** | Flex column, centered | ~400–600px | h2 (70px, "Sign up to get your..."), CTA buttons (Log in, Sign up, Continue with Google/Facebook) | extracted |
| 3 | **Feature Imagery Grid** | Masonry / CSS columns | ~600–900px | Pin cards, overlapping visual mosaic | inferred |
| 4 | **Category / Interest Explorer** | Horizontal scroll or grid | ~200–300px | Interest chips with pill radius (`--pintrest-radius-full`), category labels | inferred |
| 5 | **Footer** | Flex row, full-width | ~100–160px | App store links (iOS/Android), Explore link, Terms of Service, Privacy Policy | extracted |

### 5.2 Layout Patterns

**Navigation (extracted):**
```
display: flex;
flex-direction: row;
justify-content: space-between;
align-items: center;
padding: 16px;                    /* --pintrest-space-lg */
background-color: #fff;           /* --base-color-grayscale-0 */
width: 100%;
```
Logo anchored left, action buttons (Log in, Sign up) anchored right. Intermediate space-between places search or nav links in the centre.

**Hero / Auth Panel (extracted from computed styles):**
```
/* Centred column, text-align: center on h1 */
h2: font-size: 70px; font-weight: 600; color: #fff; text-align: start;
h1: font-size: 28px; font-weight: 700; color: #000; text-align: center; padding: 0 16px;
CTA buttons: inline-block; padding: 6px 14px; border-radius: 16px; background: #e60023;
```

**Modal / Sheet (extracted):**
```
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;
/* Scrim: --sema-color-background-scrims-opaque (hsla(53,29%,95%,.8)) */
```

**Pin Card Grid (inferred):**
- Masonry layout, variable card heights
- Cards use `border-radius: --pintrest-radius-lg` (16px)
- Image overlay gradients: `--sema-color-background-gradient-darken-bottom-weak`
- Card hover: scale transform or shadow elevation change with `--pintrest-duration-fast`

**Interest/Category Chips (inferred):**
- `border-radius: --pintrest-radius-full` (999px)
- Background: `--base-color-grayscale-50`
- Active/selected: `--base-color-grayscale-100` or Pinterest red tint

### 5.3 Visual Hierarchy

1. **Hero headline (70px, weight 600, white)** — most visually dominant element; placed over image background
2. **Pinterest red CTA buttons** — singular colour contrast moment; `background: #e60023`; all other buttons are secondary (neutral/transparent)
3. **Navigation bar** — white, slim, hugs top edge; logo (Pinterest red P) is the only persistent brand moment
4. **Pin imagery** — user content dominates below-the-fold; UI withdraws
5. **Footer links** — `font-size: 12px; color: rgb(33,25,34)` — deliberately low-contrast

**CTA placement:** Primary CTA ("Log in", "Sign up") in top-right nav AND in the hero panel. Both use `--base-color-pinterest` background.

**Whitespace rhythm:** `padding: 16px` on nav, `0 16px` on h1. Section gaps approximate `--pintrest-space-3xl` (48px) between major sections.

### 5.4 Content Patterns

**Auth Button Group (repeated in nav and hero):**
- "Log in" → secondary style (neutral background or outline)
- "Sign up" → primary style (`#e60023` background)
- "Continue with Google" / "Continue with Facebook" → transparent/ghost with social icon

**Legal Footer Links:**
- Pattern: `font-size: 12px; font-weight: 400; color: rgb(33,25,34); text-decoration: none;`
- On hover/focus: `text-decoration-line: underline` (from `.eTLu1g:focus, .eTLu1g:hover`)

**Pin Card Hover Overlay:**
- Dark bottom gradient (`--sema-color-background-gradient-darken-bottom-weak`) revealed on hover
- "Save" button appears — uses `--pintrest-radius-full` (pill shape)

## 6. Component Patterns

### 6.1 Primary Button

**Anatomy:** `[container] > [label]`
- Container: `inline-block`, `border-radius: 16px`, `padding: 6px 14px`, `background: #e60023`
- Label: `font-family: Pin Sans`, `font-size: 16px`, `font-weight: 700`, `color: #fff`
- Invisible focus border: `border: 2px solid transparent`
- Transition: `transform 0.085s ease`

**State Table:**

| State | Background | Text | Border | Transform |
|---|---|---|---|---|
| Default | `#e60023` | `#fff` | `2px solid transparent` | `scale(1)` |
| Hover | `#cc001f` | `#fff` | `2px solid transparent` | `scale(1)` |
| Active/Pressed | `#b2001b` | `#fff` | `2px solid transparent` | `scale(0.95)` |
| Focus | `#e60023` | `#fff` | `2px solid #000` (focus-visible) | `scale(1)` |
| Disabled | `#e5e5e0` | `#91918c` | `2px solid transparent` | `scale(1)` |
| Loading | `#e60023` | transparent (spinner) | `2px solid transparent` | `scale(1)` |

## 7. Elevation & Depth

### Shadow Tokens

```css
/* ── Elevation Shadows ── */
/* extracted: high confidence */
--sema-elevation-shadow-surface:  0px 0.5px 3px  0px rgba(0,0,0,.2);  /* Lowest — cards on surface */
--sema-elevation-shadow-raised:   0px 1.5px 6px  0px rgba(0,0,0,.2);  /* Raised — dropdowns, popovers */
--sema-elevation-shadow-floating: 0px 3px   12px 0px rgba(0,0,0,.2);  /* Floating — modals, tooltips */
```

### Blur Tokens (Backdrop Filter)

```css
/* ── Background Blur ── */
--sema-elevation-background-blur-weak:   8px;   /* Subtle glass effect */
--sema-elevation-background-blur-default: 24px; /* Standard backdrop blur */
--sema-elevation-background-blur-strong: 64px;  /* Heavy blur — strong glass overlays */
```

### Z-Index Scale (inferred from layering needs)

```css
/* reconstructed: moderate confidence, inferred from component types */
--z-base:      0;     /* Standard document flow */
--z-raised:    10;    /* Cards, raised surfaces */
--z-dropdown:  100;   /* Dropdown menus, popovers */
--z-sticky:    200;   /* Sticky navigation */
--z-overlay:   300;   /* Overlay / scrim layer */
--z-modal:     400;   /* Modal dialogs, sheets */
--z-toast:     500;   /* Toast notifications */
--z-tooltip:   600;   /* Tooltips (highest) */
```

### Scrim Tokens

```css
--sema-color-background-scrims-opaque:      hsla(53,29%,95%,.8);   /* Light scrim — auth sheets */
--sema-color-background-scrims-translucent: hsla(60,2%,45%,.4);   /* Dark translucent scrim */
/* Hover states */
--sema-color-hover-background-scrims-opaque:      hsla(60,6%,83%,.8);
--sema-color-hover-background-scrims-translucent: rgba(51,51,46,.4);
/* Pressed states */
--sema-color-pressed-background-scrims-opaque:      hsla(60,3%,74%,.8);
--sema-color-pressed-background-scrims-translucent: rgba(29,29,27,.4);
```

### Border Tokens

```css
/* ── Focus Ring ── */
/* Outer ring: 2px solid var(--sema-color-border-focus-outer-default) */
/* Inner ring: 2px solid var(--sema-color-border-focus-inner-dark) [= #000] */
/* Focus offset: var(--sema-space-0) to var(--sema-space-50) */

/* ── Component Border Widths ── */
--comp-checkbox-border-width-container-default-unchecked: 1px;
--comp-radiobutton-border-width-container-default-deselected: 1px;
--comp-avatar-border-width-container: 1px;
--comp-avatargroup-border-width-container: 1px;
--comp-slider-border-width-handle: 2px;
/* Focus rings */
--comp-checkbox-border-width-focus-outer: 2px;
--comp-checkbox-border-width-focus-inner: 2px;
--comp-buttontoggle-border-width-focus-outer: 2px;
--comp-buttontoggle-border-width-focus-inner: 2px;
```

### Layering Principles
- **Surface shadow** (`--sema-elevation-shadow-surface`): pin cards, form containers sitting on page
- **Raised shadow** (`--sema-elevation-shadow-raised`): dropdowns, context menus, hover-revealed action panels
- **Floating shadow** (`--sema-elevation-shadow-floating`): modals, sheets, tooltip bubbles
- **Scrim**: always placed below the modal/sheet z-layer but above content; opaque variant for light mode auth flows

## 8. Motion

### Timing & Easing Tokens

```css
/* ── Durations ── */
/* extracted: high confidence */
--pintrest-duration-fast: 0.085s;   /* Primary — button press, micro-interactions */

/* ── Easing ── */
/* extracted: high confidence */

--sema-motion-bezier-easing-ease-in-out: cubic-bezier(0.8, 0, 0.2, 1);      /* Symmetric — modal open/close */
--sema-motion-bezier-easing-linear:      cubic-bezier(0, 0, 1, 1);          /* Spinner rotation */

/* ── Spring Easings (semantic) ── */
--sema-motion-spring-spatial-fast:   linear(/* ... */);  /* Fast spring — quick snaps */
--sema-motion-spring-spatial-medium: linear(/* ... */);  /* Medium spring — cards, sheets */
--sema-motion-spring-spatial-slow:   linear(/* ... */);  /* Slow spring — large spatial transitions */
/* Note: Full spring values are complex linear() functions. See token reference or Pinterest's CSS for full values. */
```

### Named Keyframe Animations

}
```

### Motion Usage Rules
- **Micro-interactions** (button press, toggle flip): `0.085s ease` — never longer
- **Enter transitions** (modal, sheet, dropdown): slide + fade, `ease-out` curve, 150–200ms
- **Exit transitions**: slide out or fade out, `ease-in` curve, same duration
- **Skeleton shimmer**: 1.3s cycle via `M_GEGK`
- **Spinner**: continuous `rotate(360deg)` linear
- **NEVER animate** `width`, `height`, or `top/left` for layout — use `transform` only
- **Respect** `prefers-reduced-motion`: disable springs and slides, keep only opacity fades at ≤100ms

## 9. Anti-Patterns & Constraints

1. **Using system fonts as the primary typeface → Why it fails:** AI agents default to `font-family: Inter, sans-serif` or `font-family: -apple-system, sans-serif` without explicit instruction. This produces output that looks like a generic dashboard, not Pinterest. The entire UI hierarchy depends on "Pin Sans" as the lead family. → **What to do instead:** Always write `font-family: var(--base-font-family-default-latin)` which resolves to `"Pin Sans", -apple-system, ...`. Never write `font-family: Inter` or `font-family: system-ui` on any Pinterest component.

2. **Hardcoding colour hex values → Why it fails:** AI agents frequently inline `#e60023` or `#cc001f` directly in JSX `style` objects. This bypasses the token system — if the brand red shifts, every hardcoded value breaks silently while token-referenced elements update correctly. → **What to do instead:** Always write `var(--base-color-pinterest)` for the brand red, `var(--base-color-hover-pinterest)` for hover, `var(--base-color-pressed-pinterest)` for active. Never hardcode any hex value that has a named token.

3. **Applying arbitrary spacing values → Why it fails:** AI agents generate `padding: 20px` or `gap: 15px` because those feel "round". Pinterest's spacing system includes intentional off-grid values (10px, 14px) that reflect its token scale — substituting them with 8px/16px nearest-neighbours changes the visual density and breaks the system's internal consistency. → **What to do instead:** Use only the 7-token spacing scale (`--pintrest-space-sm` through `--pintrest-space-3xl`). For button padding use the computed value `6px 14px` exactly; for input padding use `11px 15px` exactly.

4. **Constructing Tailwind class names dynamically → Why it fails:** Tailwind's JIT compiler scans source code for complete class strings at build time. Writing `` `bg-[var(--${token})]` `` or `bg-[var(--base-color-${variant})]` produces classes that never appear in the compiled CSS, resulting in unstyled elements at runtime. → **What to do instead:** Write complete, static class names: `bg-[var(--base-color-pinterest)]`. Or use CSS custom properties in `style` props directly for dynamic values.

5. **Missing the three-state colour pattern on interactive elements → Why it fails:** Pinterest defines separate colour tokens for `default`, `hover`, and `pressed` states for every interactive surface. AI agents commonly implement only default + hover, skipping the `pressed/active` state. Users notice the missing press feedback immediately. → **What to do instead:** Every button, link, and interactive control must implement all three: default (`--base-color-pinterest`), hover (`:hover` → `--base-color-hover-pinterest`), and active (`:active` → `--base-color-pressed-pinterest`).

6. **Using border-radius values outside the defined scale → Why it fails:** AI agents generate `border-radius: 8px` because it's common, or `border-radius: 50%` for circles. Pinterest's radius scale is specific: 2px (badge), 12px (chips/some CTAs), 16px (primary buttons and inputs), 999px (pill chips). Using 8px on a button makes it look like a generic SaaS UI, not Pinterest. → **What to do instead:** Reference `var(--pintrest-radius-sm/md/lg/full)` for every rounded element. Primary buttons and inputs are always `var(--pintrest-radius-lg)` (16px). Pill chips are always `var(--pintrest-radius-full)`.

7. **Applying gradient backgrounds to UI surfaces → Why it fails:** Pinterest's dark-overlay gradients (`--sema-color-background-gradient-darken-bottom-*`) exist exclusively to darken imagery for text legibility. AI agents misread these as brand surface gradients and apply them to card backgrounds, nav bars, or hero sections, producing a "photo app" look that conflicts with Pinterest's clean-surface philosophy. → **What to do instead:** Surface backgrounds are always flat values from the grayscale scale. Gradients only go on top of photographic images as overlay layers, never on UI surfaces.

8. **Using `position: absolute` for primary layout → Why it fails:** AI agents reach for `position: absolute` when positioning elements within cards or navigation, which breaks at different viewport widths and causes overflow clipping on the masonry grid. → **What to do instead:** Use `display: flex` with `justify-content: space-between` for navigation, and CSS columns/grid for pin layouts. Reserve `position: absolute` only for overlays placed on top of images (save buttons, overlay gradients).

9. **Omitting focus-visible states → Why it fails:** Pinterest's system uses a two-ring focus indicator (outer ring + inner ring, each 2px). AI agents commonly set `outline: none` to avoid the browser default ring without replacing it with the Pinterest ring pattern, making the UI inaccessible. → **What to do instead:** All focusable elements must have `:focus-visible { outline: 2px solid var(--sema-color-border-focus-outer-default); outline-offset: var(--sema-space-50); }`. Interactive components that need the inner ring must also apply the inner border with `box-shadow` inset.

10. **Applying `!important` overrides to theme tokens → Why it fails:** Pinterest's system relies on the cascade of `base → semantic → component` tokens. Overriding with `!important` at the component level breaks state-dependent token resolution (hover/pressed states stop working because the default value is locked). → **What to do instead:** Override by increasing specificity with a parent selector, or by redefining the semantic token at the component scope with `:root [data-component="x"] { --sema-token: new-value; }`.

11. **Placeholder content in production components → Why it fails:** AI agents fill in `Lorem ipsum` text, placeholder image URLs (`https://via.placeholder.com/...`), and generic icon paths. Pinterest's UI is content-driven; using placeholders hides layout issues (especially in the masonry grid where variable image heights are fundamental). → **What to do instead:** Use realistic variable-height content in development. For image placeholders, use `background-color: var(--base-color-grayscale-100)` with aspect ratios, not external placeholder services.

## Appendix B: Token Source Metadata

```
tokenSource:       extracted-css-vars
sourceURL:         pinterest.com (pinterest.com — Note: "pintrest" is a typo in the kit prefix)
totalExtracted:    1865 CSS custom properties
curatedCount:      38 tokens mapped to standard roles
confidenceLevel:   high
extractionDate:    [TBD - confirm extraction date]

curatedTokenPrefix: --pintrest-* (synthetic aliases for curated set)
originalNamesPreserved: YES — all --base-*, --sema-*, --comp-* names used verbatim

noteOnOffGridSpacing:
  Pinterest's spacing system includes intentional off-grid values:
  10px (--sema-space-250) and 14px (--sema-space-350) appear in button padding
  and component contexts. These are NOT errors — they are deliberate brand values.
  The auto-detected anti-pattern warning about off-grid spacing should be interpreted
  as a caution against ADDING new off-grid values, not removing existing ones.

noteOnColourBloat:
  857 near-duplicate colour pairs exist in the full token set. The curated
  17-token colour set is the canonical working set. The full primitive scales
  (base-color-*-50 through -700 for each hue) exist for state derivation in
  component tokens, not for direct use in new components.

noteOnFontWeightMapping:
  --pintrest-font-weight-medium maps to 600 in the curated set, but
  --base-font-weight-500 (500) is the system's true "medium" weight.
  The 600 value was extracted from the h2 computed style (font-weight: 600)
  which is a display-specific weight, not the semantic medium weight.
  USE --base-font-weight-500 (500) for UI medium; use 600 only for display headings.

noteOnSpaceXs:
  --pintrest-space-xs is incorrectly mapped to 64px (--sema-space-1600) in the
  curated token set. 64px is a backdrop-filter blur value, not a spacing value.
  DO NOT USE --pintrest-space-xs for layout spacing. Use --pintrest-space-lg (16px)
  as the minimum meaningful layout spacing token.
