brand-to-tokens

The brand→token derivation — the first consumer demand that closes the ADR-061 §8 deferral. Takes a confirmed brand-identity constraint set and produces a DTCG tokens.json source of truth, then hands it to the design-tokens toolchain to emit CSS vars + Tailwind. The same tokens.json is the export that pack-ai-image brand-asset generation and the greenfield scaffold seed consume (B → A; contract: brand-token-consumption).

When to use

• A confirmed brand identity (colour story, type story, spacing) needs to become a maintained token system.
• A consumer asks to "turn the brand into tokens / CSS variables / a theme."
• Before pack-ai-image brand-asset generation or a greenfield scaffold needs the tokens.json export.

Procedure

1. Take the confirmed brand-identity constraint set — colour story (roles + values), type story (heading/body classes), spacing/radius intent. If a consumer brand profile already registers values, those win (brand-source-of-truth).

2. Author tokens.json on the design-tokens 3-layer DTCG model ($value / $type): brand palette → primitive.color.*; brand roles (primary, accent, surface, destructive) → semantic.color.* referencing the primitives; per-widget needs → component.*. Add dark.semantic.* overrides. Type tokens come from typography-system stage-2 (archetype → pairing-filter), added under the typography section.

3. Generate CSS vars + Tailwind through the toolchain:

   node <skills-root>/design-tokens/scripts/tokens.mjs generate \
     --config tokens.json -o assets/design-tokens.css
   node <skills-root>/design-tokens/scripts/tokens.mjs generate \
     --config tokens.json --format tailwind
   

4. Validate — node <skills-root>/design-tokens/scripts/tokens.mjs validate --dir src/ until clean (exit 0 is the evidence); convert hardcoded values to var(--token).

5. Export the deck templates — emit the locked-variable brand deck templates from templates/ — marp-brand-deck.md.example (copy to .md to use) and reveal-brand-deck.yaml — substituting the brand variables from tokens.json. No render engine is owned (decision 7); the templates feed the user's own deck tool.

6. Publish tokens.json as the source of truth other surfaces read (pack-ai-image generation, greenfield scaffold) per the consumption contract.

Output format

1. tokens.json — DTCG 3-layer (primitive → semantic → component) + dark.semantic + typography, every value {$value, $type}.
2. Generated design-tokens.css + the Tailwind theme.extend snippet.
3. validate evidence — exit 0, or the token_violation findings handed to polish.
4. The exported brand deck templates (Marp + reveal) with brand variables locked from the tokens.

Gotcha

• tokens.json is the single source — never hand-edit the generated CSS or a consumer-side copy. pack-ai-image generation and the greenfield scaffold read this file; a hand-edited downstream copy silently drifts from the brand.
• Derive, do not invent. Every token traces to a brand-identity decision or the consumer's existing brand; a value with no brand provenance is off-brand (brand-source-of-truth § Iron Law 2 flags it).
• Deck templates lock brand variables — never inline a raw hex/font in a template; reference the token so the deck stays on-brand when tokens change.

Do NOT

• Do NOT generate marks or assets here — this skill emits tokens + templates; logo-generation / brand-asset-generation generate the marks from the tokens (B → A, never inverted).
• Do NOT hand-edit generated CSS — tokens.json is the source.
• Do NOT let components reference primitives directly — semantic layer between.
• Do NOT own a slide-render engine — export validated templates only (decision 7).
