Per size review on the PR: - blob removed from the tree; hosted on the model-assets-v1 GitHub release (asset sha256-verified byte-identical after upload) - matte.cjs resolves: MATTE_MODEL env -> legacy bundled copy if present -> ~/.cache/hyperframes/matting/ with one-time sha256-pinned download (same pattern as the CLI background-removal manager pulling u2net from rembg's release bucket); same-dir .part temp + atomic rename - new `matte.cjs --ensure-model` pre-warm flag; SKILL.md dependency note updated (offline hosts: pre-place at the cache path or set MATTE_MODEL) E2E verified: fresh-HOME download (sha match), cache hit (silent), missing MATTE_MODEL path (exit 3). Author-time fetch only — render path untouched. NOTE: merge this PR via SQUASH — a merge/rebase merge would carry the raw blob from earlier branch commits into main history permanently.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(cli): clear fallow audit gate (PR #1349 CI) Two parts: - validate.ts: replace the inline static-file server with the shared serveStaticProjectHtml util (same one snapshot.ts / layout.ts use).

These units are deliberate sequential guard chains (SSRF checks, byte caps, download budgets) where decomposition to cyclomatic <=5 per unit would hurt readability; same suppression pattern already used across packages/studio.

chromeFontsmakes the doc chrome render in the preset's native fonts; brand fonts still apply to §6 components. Scatterbrain has no machine-mono moment — themonoslot points at Caveat per §D's three-slot contract.
§A Director's intent
Designer's whiteboard at 11am. Sticky notes pinned to cork, masking tape across the corner, marker doodles in the margins. Shrikhand display reads as chunky marker-pen lettering; Zilla Slab body sits like a printed handout; Caveat is the moment something got jotted down.
Depth is soft blurred drop-shadow (2px 3px 15px shadow, 0 1px 3px shadow-deep) on every post-it — the rare preset that embraces blur because the visual depends on paper lifting off cork. Every sticky carries a small rotation (±1° to ±15°) and a thumbtack pin via ::before; hero stickies add a translucent tape strip via ::after.
Brand DNA tints the stickies; preset anchors keep the register playful. Three site colors (--brand-primary / --brand-secondary / --brand-accent) mix with named pastel anchors (--anchor-butter / --anchor-sky / --anchor-blush / --anchor-mint) so dark or oversaturated brands still produce sticky-note pastels instead of muddy fills. Cream paper (--paper-cream) and warm ink (--ink-warm) are technical prerequisites — pure white kills the tactile register; pure black on warm pastels reads cold.
Color role contract: post-its cycle through the four anchor-mixed pastels (butter, sky, blush, mint) for categorical variety; brand DNA flows in as gradient deepening, pin colors, and feature-icon accents. Ink-warm carries every headline, every body line, every border, every doodle — colored text on pastel stickies kills legibility.
Motion is hand-placed tilt: short overshoot on entry (the sticky "lands" with a tiny bounce), no glide. Doodles drift on sine.inOut. Scene transitions are quick cuts with a single tape-rip beat — never crossfade.
Class prefix: sb- (initialism, 3 chars per §8.6).
Atmosphere is non-negotiable. Every scene gets the grain overlay + one of three background variants (cork / paper / warm). A post-it floating on plain white reads as broken — the textured ground IS the system.
§B Decoration tokens (merge into design.html :root)
Scatterbrain declares structural tokens here (sticky-note shadow stack, rotation tilts, pin / tape geometry, doodle stroke). Color comes mostly from brand DNA mixed against named pastel anchors so the playful register survives any brand palette.
The cream paper base (--paper-cream) and warm ink (--ink-warm) are technical exceptions: pure white loses the paper texture, pure black on warm pastels feels cold. The four anchor hues are §8.2 hue-anchor tokens — declared once, mixed against brand vars in every component — so the system stays "sticky-note" regardless of brand DNA.

§D Font pairing fallback (if brand fonts not on Google Fonts)
Scatterbrain forces its display / body / script regardless of site DNA — the workshop voice depends on Shrikhand's chunky decorative shapes, Zilla Slab's warm slabs, and Caveat's casual cursive. Fallbacks below are only used if the primary face fails to load.
- display:
'Shrikhand'·'Fraunces'·'Lobster'wght 400 - body:
'Zilla Slab'·'Roboto Slab'·'Bitter'wght 400 - mono:
'Caveat'·'Patrick Hand'·'Kalam'wght 500
(The "mono" slot is reused for the script face — Scatterbrain has no monospace need, but resolveFont() reads three roles. The fallback chain stays on hand-script.)
§T Type-role atlas (Phase 4b reads this to size text correctly)
The atlas is the sole authoring source for non-component text. If a scene needs a stat-value numeral that isn't covered by §6 components, the worker reads role stat-value here and writes inline CSS from these values. Do NOT invent ad-hoc sizes — Scatterbrain's identity collapses if Shrikhand drops out of headline roles or if body copy slips into Shrikhand.

§E Motion (GSAP consts — REPLACES site ease)
const EASE = {
entry: "back.out(1.6)", // sticky "lands" with a tiny bounce — hand-placed feel
emphasis: "back.out(1.4)", // pin/tape attach beats, doodle reveals
exit: "power2.in", // sticky lifts off cleanly on exit
drift: "sine.inOut", // doodle / handwritten quip ambient sway
};
const DUR = {
snap: 0.18,
med: 0.5,
slow: 0.9,
};
// RULE: entry uses back.out — the sticky must land with a small overshoot.
// Never ease-in-out for primary motion; the sticky reads as floating instead of pinned.
// RULE: tilt is part of the resting state, NOT animated. Set transform: rotate(<tilt>)
// at scene start; do not tween rotation between values. The whole point is "hand-placed
// and left alone" — a sticky that wiggles reads as broken.
// RULE: scene transitions are quick cuts (≤ 0.18s) with a tape-rip beat. No crossfade,
// no slide between scenes — crossfade kills the tactile register.
// RULE: pin attaches AFTER the sticky lands. Stagger pin reveal ~80ms behind the sticky
// so the eye reads "sticky placed → pin pressed in".
§E.5 Motion choreography
Allowed primitives
- Sticky entry:
back.out(1.6), ~0.5s, from offset (translateY +24px, opacity 0). Tilt is set at landing, not animated. - Pin attach:
back.out(1.4), ~0.18s, scale 0 → 1, ~80ms after sticky lands. - Tape attach: same as pin but ~120ms later, with a tiny rotation jiggle (-3° → -2°).
- Handwritten Caveat lines reveal with a brief x-offset (translateX -8px → 0) on
power2.out. - Doodle stroke drift:
sine.inOut, ~3s, ±2° rotation around its center — ambient only. - Stat numerals: count-up on
power2.out, ~0.6s, snap to final value.
Forbidden
- Crossfade, dissolve, blur transitions between scenes.
- Sub-degree rotation tweens on a sticky (a sticky that wiggles reads as broken).
- Glow, neon, hard-offset zero-blur shadows (the wrong preset).
- Border-radius on post-its (every sticky is a rectangle, only icons / pins / versus-circles are round).
- More than 6 post-its visible at once — the playful energy collapses into chaos.
- Uniform tilt direction across adjacent stickies — alternate ± per neighbor.
Stagger budget
120-160ms between cluster items (sticky → pin → tape, then next sticky). Total scene-in stagger ≤ 700ms. Doodles always last, after all stickies have landed.
§G Voice transform recipe
Take the brand's product description / value prop. Transform with:
- Strip corporate hedges ("solution", "platform", "leverage", "synergy"). Keep concrete nouns + verbs.
- Hero headlines: 2-5 words, mixed case (NOT uppercase — Shrikhand is loud enough; uppercase reads as shouting and kills the workshop register).
- Eyebrow labels: short categorical words in Caveat, UPPERCASE with 0.15em tracking (
THE BRIEF,CHAPTER ONE,01 / DISCOVERY). This is the only place uppercase appears. - Body paragraphs: Zilla Slab sentence case, conversational. Write like a designer explaining their notes to a peer, not like marketing copy.
- Personal quips in Caveat: 2-6 words, lowercase, with personality ("jot it down before you forget", "pin this somewhere safe", "ok :)"). One per scene maximum.
- Stat values: numeric + UPPERCASE one-word unit (
128K USERS,4.8 STARS). Stat labels in Zilla Slab sentence case.
Example:
- IN:
Figma helps teams design products collaboratively in real time - OUT: hero=
Design together./ eyebrow=THE TEAM SPACE/ body=Every cursor, every comment, every revision — visible to the whole crew./ quip=like a whiteboard, but online :)
