tokens

CSS custom property catalog — machine-readable index of --chirpui-* tokens. Each `TokenDef` records a single CSS custom property: its name, semantic category, and scope (global or a component block name). The catalog is bootstrapped by ``scripts/extract_tokens.py`` and curated here as the source of truth. Tests validate it against ``chirpui.css`` to catch drift. Categories ---------- * **color** — semantic colors, state colors, gradients * **spacing** — fluid spacing scale and role aliases * **typography** — font sizes, weights, families, line-heights * **radius** — border-radius scale * **elevation** — box-shadow tokens * **motion** — easing curves and durations * **layout** — structural tokens (container max, grid min, sidebar dims) * **component** — per-component override knobs (scoped)
