/* ── Starosphere flow-UI skin — star-editorial v1 (DESIGN-LOCK-V1, W-D0) ───────
 * The stranger's-first-60s surfaces: sign-in · onboarding · empty-state · OS
 * picker · custom-app composer. GOVERNING IDEA: a warm printed almanac made
 * operational — bond-cream plaza ground, press-umber ink, ONE cadmium act per
 * surface, elevation drawn as an ENGRAVED HAIRLINE (a 1px printed rule + faint
 * warm cast), never a drop shadow. Editorial calm, not console dark.
 *
 * IDENTITY SOURCE OF TRUTH: packages/theme/src/design/languages/star-editorial.ts
 * (operator-ratified 2026-07-07). Every value below mirrors that language verbatim:
 *   • surface ramp  ground #F5EEDD → card #EFE7D3 → raised #FBF5E6 → sunk #E4D8BC
 *   • ink           #2C2118 / #5A4A38 / faint umber (never #000)
 *   • the ONE act   cadmium #DD5A2A (<40% area), deep #B8461E on press
 *   • engraved line #CBB799 rest / #B9A886 strong
 *   • ZERO-RADIUS   v3 ratified 2026-07-07 — sharp, carved-block corners
 *                   (architectural instrument precision, not soft app-chrome)
 *   • VOICE         Space Grotesk UI + IBM Plex Mono data; serif display awaits
 *                   Fraunces self-hosting (Georgia fallback — matches the live
 *                   chrome, which is NOT yet self-hosting either)
 *   • MOTION        Cold Press Settle — calm easeOut, printed, confident
 *
 * SCOPING: the star-editorial `--star-*` values are declared on `.sph` (NOT global
 * :root) so these overlays carry the ratified identity WITHOUT reskinning the
 * booted OS underneath. Provenance mirror: src/starosphere-tokens.css.
 * Law: NO Inter · NO purple/blue AI gradient · NO pure black · NO glassmorphism.
 * GPU-safe motion only (transform/opacity). Every control: hover/active/focus.
