  Video-first companion to Coral's design.md. The unit is the frame (1920×1080), not the
  slide-in-a-deck. Atoms are identical and sacred — the three-surface system (coral fire /
  ink black / warm cream), Bebas Neue uppercase tracked + Inter body, the 45° diagonal hatch,
  decorative wallpaper numerals, hard color-region splits, zero shadow, zero radius (save
  circles). Composition, frame scale, and aspect-ratio behavior are rewritten for the frame.
  Motion is out of scope.

# Coral — Frame (video / frame layer)

## Overview

Coral at frame scale is a **bold magazine poster** built from three solid surfaces — coral fire,
ink black, warm cream — that meet at **hard color edges.** The region boundary IS the layout: a
frame splits into a coral plane + a cream plane, or a coral panel + an ink panel, each holding a
self-contained composition. No gradient transitions, no rounded junctions, no drop shadows.

The voice is a two-face hierarchy: **Bebas Neue** — tall condensed caps, always uppercase, always
tracked (1–12px) — carries every headline, stat, title, and meta figure; **Inter** carries every
body line, label, and attribution across weights 300–700. Bebas declares; Inter explains. The
signature atmospherics are the **45° diagonal hatch** (6% ink) over coral regions and the
**oversized wallpaper numeral** (12% ink) behind a region's title.

**Key characteristics at frame scale:**

- **Three surfaces, hard edges** — `{colors.coral}` / `{colors.black}` / `{colors.cream}` as solid regions.
- **Bebas uppercase + tracking** on every display element; **Inter** on every body/label.
- **45° hatch** (6% ink) on coral regions; **wallpaper numerals** (12%) and **giant marks** (35%) behind content.
- **Ink-on-fire** — Bebas on coral is always ink, never white. Eyebrows coral on cream/ink, ink on coral.
- **Flat** — no shadow, no elevation; radius only on circles (nav dots, timeline nodes).
- **Coral as accent AND environment** — 4–5px coral borders, 48px coral icon squares, and full coral regions.

### Frame Craft Bar

Three eyeball tests gate every frame before any structural check:

- **Squint** — one element dominates at **3–6× its nearest neighbor**: the `hero-title`/`jumbo-feature` or a wallpaper numeral behind a region's title, never two rival headlines.
- **Silence** — coral/cream/ink regions read **40–55% empty**; the **three-column catalog is the one dense exception**. A coral region underfilled gets a wallpaper numeral, never more content.
- **Restraint** — coral fires as **either accent or one full region per frame** (not both at full strength); one giant-mark per quote; ink-on-fire (never white on coral).
- **Reference** — aim at a **sports-magazine cover / Saul Bass travel poster** (solid planes at hard edges, condensed caps as architecture); failure looks like a **soft drop-shadowed card deck**.

## The Frame

- **Primary:** 1920×1080 (16:9). Display sizes authored in **`cqw`** (`px ÷ 1920 × 100 = cqw`).
- **Vertical:** 1080×1920 (9:16). **Square:** 1080×1080 (1:1).
- **Safe area:** `5cqw` (pad-x) standard frame padding; region edges may bleed full-frame.

**The container law (load-bearing).** Every frame ground sets `container-type: size`; ALL
frame-relative units are `cqw`/`cqh` resolved against it — **never `vw`.** A `vw`-sized frame
inflates whenever it isn't full-screen; `cqw` resolves against the frame at any render size.

## Colors

Tokens identical to the source. At frame scale the three surfaces are intermixed by composition —
coral/cream, coral/ink, ink/cream, or single-surface. `{colors.coral}` is both accent (borders,
icon squares, timeline nodes, eyebrows on cream/ink) and environment (full regions). Headlines:
ink on cream/coral, cream on ink — **never gray, never white-on-coral.** Eyebrows: coral on
cream/ink, ink on coral — coral-on-coral does not exist. The only sanctioned gradient is the rare
135° coral-dark→coral feature region; everything else is flat.

## Typography

Two ramps. The **reading ramp** (Inter body 1.0cqw, body-light 1.5cqw, labels in px) carries copy
and eyebrows; the **display/hero ramp** (Bebas, `card-title` 1.9cqw → `jumbo-feature` 9.0cqw, plus
the decorative `background-numeral` 10cqw and `giant-mark` 14cqw) carries every headline and stat.

- **Legibility floor:** any load-bearing line ≥ **1.4cqw**; px labels are chrome only.
- **Fit-to-measure:** size the headline to its line length. Cap the block at **≤ 78cqw**; ≤3 words → `hero-title`/`jumbo-feature`; 4–6 → `section-headline`; 7+ → `column-title`.
- **Every Bebas element is uppercase with ≥1px tracking** (2px standard, 4px hero, 12px jumbo). **Every Inter label is uppercase, 1–4px tracked.** No italic, no underline, no sentence-case Bebas.

## Depth & Surface

Flat, with hard color edges. Depth signals only:

- **Hard region boundaries** — the primary structural device.
- **Accent borders** — 5px coral top (cards), 4px coral left (sidebar tiles), 4px ink (timeline).
- **45° hatch** — 6% ink texture on coral regions (no depth).
- **Wallpaper typography** — numerals at 12%, giant marks at 35%, layered behind content.

**Ceiling:** no box-shadow, no elevated card, no soft gradient (save the one 135° coral feature), no rounded rectangle.

## Shapes

- **0 radius** on every rectangle — regions, cards, sidebar tiles, icon squares, info bars, accent lines.
- **50%** on circles only — nav dots (10px), nav arrows (44px), timeline nodes (20px).

## Components

- **region-split** — the layout device; surfaces meet at a hard edge.
- **card** (5px coral top) / **sidebar-item** (4px coral left) / **card-icon** (48px coral square) — the only chrome on each is its single coral border.
- **diagonal-hatch** / **background-numeral** / **giant-mark** — the atmospheric + wallpaper signatures on coral regions.
- **accent-line** — coral sub-headline rule. **timeline** — ink line, coral nodes, cream halos. **info-bar** — cream-dark footer band.

## Frame Treatments

> Recipe per plate: ground · container · composes · focal · chrome · accent · silence · Fixed/Free · density.
> Lean centered where the move allows; vary anchor; one idea per region.

### 1 · Region-Split Cover (identity · move: hard region edge · left)

**Ground** 38/62 split — `{colors.coral}` top band (hatch + wallpaper numeral) over `{colors.cream}`.
**Container** grid rows; brand + meta in the coral band, hero title in the cream field. **Composes**
region-split, diagonal-hatch, background-numeral, hero-title. **Focal** a 2-line `hero-title` in
ink, second line in `{colors.coral}`, left-anchored in the cream field. **Chrome** Bebas brand left

- Bebas meta right in the coral band. **Accent** coral band + coral second line. **Silence** the
  cream field ~45% empty. **Fixed** ink-on-fire in band, hatch on coral, hard edge. **Free** title
  copy, which line is coral, meta. **Density** sparse.

### 2 · Feature Stat (anchor · move: scale · coral environment · left)

**Ground** full `{colors.coral}` with hatch. **Composes** diagonal-hatch, background-numeral,
section-label, stat headline, body-light. **Focal** a `stat-numeral`/`jumbo-feature` figure or
2-line headline in ink, with a `background-numeral` (12% ink) behind it as wallpaper. **Chrome** an
ink `section-label` eyebrow; an optional Inter-300 support line ≤44cqw. **Accent** the coral ground
IS the environment; ink type, no white. **Silence** ~40% of the coral field empty. **Fixed**
ink-on-coral, hatch present, wallpaper numeral behind. **Free** the figure, headline, support copy.
**Density** sparse.

### 3 · Quote Layout (quote · move: panel split · giant mark)

**Ground** 40/60 split — `{colors.coral}` left panel (hatch + giant-mark) + `{colors.black}` right
panel. **Composes** region-split, giant-mark, body-light, accent-line, quote-attribution.
**Focal** a 2–3 line pull quote in `{colors.cream}` Inter **weight 300** on the ink panel.
**Chrome** a `giant-mark` (35% ink) on the coral panel; a `60×4` coral accent-line above the
attribution. **Accent** coral panel + coral accent-line. **Silence** the coral panel is mostly the
mark. **Fixed** Inter-300 quote, ink panel, ink-on-coral mark. **Free** quote, attribution, mark
glyph. **Density** sparse.

### 4 · Closing Plate (closer · move: cream field + coral band · centered)

**Ground** `{colors.cream}` field with a bottom `{colors.coral}` band (hatch). **Composes**
section-label, section-headline/hero-title, accent-line, info-bar. **Focal** a 2-line sign-off in
ink, centered, with a coral `accent-line` beneath. **Chrome** an ink eyebrow above; a coral band
footer carrying a Bebas sign-off + year. **Accent** coral band + coral accent-line. **Silence**
~55% empty cream. **Fixed** centered, ink type, one coral band. **Free** sign-off copy, band
contents. **Density** sparse.

### 5 · Three-Column Catalog (catalog · move: density — the dense frame · centered head)

**Ground** `{colors.cream}` (or `{colors.black}`), `pad-x`. **Composes** section-headline, 3× card.
**Focal** a centered `section-headline` over three white `card`s (5px coral top, 48px icon square,
Bebas title, Inter body, coral stat). **Accent** the three coral top borders + icon squares.
**Silence** tight — the density exception. **Fixed** 5px coral top as sole chrome, no shadow/radius.
**Free** the three cards' content. **Density** dense-exception.

### 6 · Timeline (process · move: horizontal rail · left)

**Ground** `{colors.cream}`, `pad-x`. **Composes** section-headline, timeline. **Focal** the ink
timeline-line with 4–5 coral nodes (cream halos) and Bebas labels. **Accent** coral nodes.
**Silence** moderate. **Fixed** ink line, coral nodes, cream halos. **Free** node count, labels.
**Density** standard.

## Composition Rules

### Do

- Compose as **multi-surface region splits** — coral / ink / cream meeting at hard edges; the boundary is the layout.
- Set every Bebas element **uppercase + tracked** (2px standard, 4px hero, 12px jumbo); every Inter label uppercase, 1–4px.
- Render eyebrows **coral on cream/ink, ink on coral**; headlines ink on cream/coral, cream on ink.
- Apply the **45° hatch** (6% ink) on coral regions; fill underweight coral regions with a **12% wallpaper numeral**.
- Use the **5px coral top** (cards) / **4px coral left** (tiles) as the only chrome on those elements.
- Lean centered on cover sign-offs and catalog heads; left/panel-split on features and quotes.

### Don't

- Don't render Bebas in sentence case or untracked; don't pair it with a non-Inter body sans.
- Don't add a fourth surface, a drop shadow, an elevation, or a rounded rectangle.
- Don't put white headlines on coral (always ink) or gray headlines anywhere (gray is body/meta).
- Don't soften a region boundary with a gradient (except the rare 135° coral feature).
- Don't fill a coral region with sparse fragments — fully populate it or add a wallpaper numeral / giant mark.
- Don't blow a headline edge-to-edge — step the ramp down for long lines.

## Aspect-Ratio Behavior

| Treatment            | 16:9                       | 9:16                                 | 1:1                  |
| -------------------- | -------------------------- | ------------------------------------ | -------------------- |
| Region-Split Cover   | 38/62 rows, title left     | taller coral band, title below       | 40/60, title lower   |
| Feature Stat         | figure left, numeral right | figure top, numeral behind           | centered figure      |
| Quote Layout         | 40/60 coral+ink            | stacked: coral mark top, quote below | stacked              |
| Closing Plate        | cream + bottom coral band  | cream + taller band                  | centered, band below |
| Three-Column Catalog | head over 3-up             | head top, 3 stacked                  | head top, 2+1        |
| Timeline             | horizontal rail            | vertical rail                        | compact horizontal   |

Safe area holds the `5cqw` padding on the short edge; re-step display per ratio so no load-bearing
line drops below the 1.4cqw floor. Bebas runs ~20% wider in CJK — adjust line breaks per ratio.

## Approved Entities

No real customers, logos, or vendors are defined in the source — render any such mark as a
placeholder. The system supplies surfaces and geometry, not brands.

## Numerals & Claims (hard rule)

Never invent figures, stats, dates, or counts at frame scale. Render slots as `— figure —`,
`{metric}`, `N×`. Real numerals appear only when the script supplies them — the feature stat,
catalog, and timeline especially carry placeholders, not fabricated values. Wallpaper numerals
(01, 02…) are decorative and may be ordinal.

## Pre-Render Self-Audit

- **Squint** — one focal element per region dominates at 3–5× its neighbor.
- **Silence** — sparse frames 40–55% empty; only the catalog runs dense.
- **Surfaces** — two or three of coral/ink/cream, meeting at hard edges; no fourth surface.
- **Type** — Bebas uppercase + tracked, fit-to-measure; ink-on-coral; eyebrow color correct for surface; ≥1.4cqw floor.
- **Depth** — 0 shadow, 0 rounded rectangle; hatch + wallpaper carry texture.
- **Anchor** — centered on sign-offs/heads, panel/left on features/quotes; no 3 consecutive frames share an anchor.
- **Fabrication** — every numeral traces to the script, else placeholder.

## Known Gaps

- **Motion intentionally out of scope.** frame.md specifies composition only; timing and transitions are a later stage. The 0.6s opacity fade in the source is a deck mechanic, not a frame spec.
- **Bebas Neue + Inter via Google Fonts.** CJK pairing (ZCOOL XiaoWei / Yozai) carries over from the source's CJK section; Bebas runs ~20% wider in CJK.
- **9:16 / 1:1 are guidance**, not pixel-locked; verify the legibility floor per ratio.
- The 45° hatch, wallpaper numerals, giant marks, and timeline dash are CSS-only; no external imagery is required.
