/* app.css — the client app's visual system, authored as CSS.
 *
 * Organised by LAYER, not by page (the old tracker.css/checkin.css split was the
 * page axis and is gone). Every colour, radius, blur, and saturation references a
 * token in tokens.css — there are NO raw colour literals here, and the contract
 * check (tools/check-css.sh) fails the build if one appears.
 *
 * The glass treatment (translucent gradient + hairline inset + depth shadow +
 * backdrop blur/saturate) is composed from those tokens and written directly onto
 * each semantic component (.app, the cards, inputs, textarea, marker surfaces). The
 * recipe repeats by intent — there is no `.glass-*` abstraction class — so reskinning
 * is a token edit. (A shared primitive would be premature until a third caller needs
 * the exact same recipe; today each surface tunes its own blur/saturation step.)
 *
 * The class name is the contract between Zero (which emits structure) and this
 * file (which owns appearance); behavioural state is carried on data-* hooks, not
 * styling classes. The check (tools/check-css.sh) fails the build on: a class/id
 * emitted with no rule or a rule emitted nowhere (both directions), a var() that
 * resolves to nothing, an unused token, a raw colour, a sync-state hook that
 * disagrees across its owners, a missing/orphan asset, or an untokened chrome hex.
