@creatica/schema

The AI-legible layer: what each background looks like and how to drive it.

• params.ts — every parameter with type, range, step, and the visual effect of low/high values; per-structure narrowing of shapeType/shapePosition mirrors the editor.
• cards.ts — hand-written style cards for all 58 structures: mood, use cases, text-safe area, tips, and what generic knobs mean for this generator.
• palettes.ts — mood tags derived from the colours (dark, pastel, vivid, warm, cool, …).
• index.ts — describe(), styleCard() (Markdown), jsonSchemaFor(), catalog(), normalizeRequest() (coerces strings, clamps ranges, drops unknown keys with warnings), suggest(brief).

The parameter set per structure is derived: a key is honoured iff it appears in the structure's info.ts defaults — the same rule the editor uses to show a control.

yarn workspace @creatica/schema verify verifies every structure has a card and the normaliser round-trips.
