> `chromeFonts` makes the doc chrome render in the preset's native fonts; brand fonts still apply to §6 components. Block Frame refuses a third face — the `script` slot points at Inter.

## §A Director's intent

Block Frame is maximalist neobrutalism: every region wears a 4px solid ink
border, every elevated card carries an 8px hard offset shadow (zero blur,
solid ink), every corner is square, and the canvas cycles through five
saturated pastels — pink, blue, green, yellow, cream — plus off-white and
ink. Display is heavy uppercase Inter with negative tracking; chrome is
wide-tracked Space Grotesk in caps. Decorative tilts (±2° to ±12°),
star-bursts, stripe blocks, and dot grids puncture the grid intentionally.
Density is the rule, not the exception.

Brand-aware color contract: `--brand-primary` is the dominant pastel
ground, `--brand-secondary` is the colored-shadow accent (replaces the
template's signature yellow shadow on the close-frame), `--brand-accent`
is the CTA fill. Class prefix is `bf-` (block-frame initials).

## §B Decoration tokens

```css
/* Border ladder — 4px primary, 3px secondary, 2px atomic chrome */
--bf-border-bold: 4px solid var(--ink);
--bf-border-mid: 3px solid var(--ink);
--bf-border-thin: 2px solid var(--ink);

/* Hard offset shadow stack — solid ink, zero blur, bottom-right */
--bf-shadow: 8px 8px 0 var(--ink);
--bf-shadow-sm: 4px 4px 0 var(--ink);
--bf-shadow-hover: 6px 6px 0 var(--ink);

/* Inverted close-surface depth — only colored shadow in the system,
   aliased to brand-secondary so it follows the site palette instead
   of the template's locked yellow. */
--bf-shadow-close: 12px 12px 0 var(--brand-secondary);
--bf-shadow-close-btn: 6px 6px 0 var(--canvas);

/* Tilt vocabulary — stat cards alternate small, decorations tilt loud */
--bf-tilt-sm-l: -2deg;
--bf-tilt-sm-r: 2deg;
--bf-tilt-md-l: -8deg;
--bf-tilt-md-r: 8deg;
--bf-tilt-loud: 12deg;

/* Spacing — template's px scale, kept px for structural fidelity */
--bf-pad-card: 36px;
--bf-pad-card-sm: 28px;
--bf-pad-card-xs: 22px;
--bf-pad-card-lg: 60px;
--bf-gap-lg: 48px;
--bf-gap-md: 32px;
--bf-gap-sm: 24px;
--bf-gap-xs: 16px;

/* Decorative dot-grid pattern unit */
--bf-dot-size: 24px;
--bf-dot-radius: 1.2px;
```

## §D Font pairing fallback

- **display**: `'Inter'` · `'Archivo Black'` · `'Space Grotesk'` wght 900
- **body**: `'Inter'` · `'IBM Plex Sans'` wght 500
- **mono**: `'Space Grotesk'` · `'JetBrains Mono'` · `'IBM Plex Mono'` wght 600

## §T Type-role atlas (Phase 4b reads this to size text correctly)

Sole authoring source for non-component text; do NOT invent ad-hoc sizes — Block Frame's identity depends on the heavy-uppercase + negative-tracking + sentence-body + wide-tracked-label ladder.

## §E Motion (GSAP consts — REPLACES site ease)

```js
// RULE: motion is snap-and-hit, never slow ease-in-out for primary entrances.
// RULE: cards "punch in" — translate from -8/-8 offset with shadow growing
//       from 0 to var(--bf-shadow). Mirrors the hover lift-up signature.
// RULE: tilts are baked at rest; do NOT tween rotation during entry.
//       Tilt-then-pop reads as wobble; tilt-at-rest reads as deliberate.
// RULE: emphasis on chrome (label-pills, buttons) uses back.out(1.6) to
//       echo the hard-shadow "stamp" feel.
// RULE: never blur shadows during motion — toggle box-shadow values, do
//       not interpolate filter() or use shadow-blur tweens.

const EASE = {
  entry: "expo.out", // cards hit and stick — template uses 0.15s ease but punchier on video scale
  emphasis: "back.out(1.6)", // chrome pops (pills, buttons, stat cards) — echoes the brutalist stamp
  exit: "power2.in", // sharp exits — never linger
  drift: "sine.inOut", // ambient (dot-grid fade-in, tilt micro-sway) only
};

const DUR = {
  snap: 0.16, // chrome hover, label-pill in, button settle — mirrors template's 0.15s
  med: 0.42, // card entry, headline reveal
  slow: 0.9, // hero entry, close-frame reveal — the loudest moments
};
```

### §E.5 Motion choreography

- **Transition defaults:** hard cut between scenes is the spiritual default. If a transition is needed, punch-translate the incoming hero element with DUR.med + EASE.emphasis.
- **Type-in-motion:** display headlines reveal as a single unit (no per-
  character split). Sub-headline reveals at +0.12s with `power2.out` +
  DUR.snap. Label-pills always emphasis-pop, never linear-fade.
- **Stagger budget:** ≤6 elements in a single stagger; beyond that, group
  visually (timeline-step row, stat-grid) and animate the group as one.

## §G Voice transform recipe

1. Strip articles and connectives (the / a / of / and / with / to).
2. Break into 2-4 word noun-verb-noun fragments or single dominant nouns.
3. UPPERCASE all on-screen text that lands in display, chip, or button
   slots — sentence body stays sentence case.
4. Join fragments with `.` + linebreak for stacked impact, or em-dash
   `—` for a single beat of emphasis.
5. End headlines on a noun, not a verb — the brutalist stamp lands on the
   thing, not the action.
6. Brand name appears as the final clause, punctuated standalone.

**Example:**

- IN: `Higgsfield is the AI platform that helps creators generate stunning visuals in seconds`
- OUT: `CREATORS. GENERATE. STUNNING VISUALS — IN SECONDS. HIGGSFIELD.`

 *
 * Block Frame has no script face — the script slot points at Inter because the
 * preset refuses a third face. The fallback chain ends in a heavy grotesque
 * (Archivo Black / system-ui) that still carries the "neobrutalist mass"
 * register. Mono slot is Space Grotesk (treated as quasi-mono via wide
 * tracking + uppercase) with JetBrains Mono / IBM Plex Mono as deeper falls. */
