/*
 * SimpleSuite Drills — front-end styles (v0.4.01).
 *
 * Front-end surface — consumes the LAUNCH PAINT CASCADE tokens
 * (--shell-*) per the SimpleSuite token contract. This is what
 * gives the drill launcher and player buttons the site's active
 * brand color (Launch preset → Simple Theme chrome contract).
 *
 * Fallback chain on every token:
 *   --shell-{token}   →  --ss-{token}   →  hardcoded neutral
 *
 * When Launch is not installed, the suite falls through to the
 * neutral charcoal default. When Launch IS installed, the active
 * preset's palette paints these surfaces automatically — buttons,
 * progress, focus states, quiz feedback.
 *
 * Scoped under .sst-drills. No border-radius, no shadows, no
 * gradients — per SS UI primitives contract.
