/* ============================================================
 * FIELD · Color tokens
 * Damaros is mineral, dark, and spatial — "calm, precise,
 * expensive." Light is never decoration. One stone-blue signal
 * (steel) carries structure; semantic colors are restrained and
 * reserved for trial state (PASS / REVIEW / FAIL) and governance.
 *
 * Two real surfaces share this palette:
 *   · damaros.ai (the public field)  — jet backgrounds, Archivo
 *   · Node / Console (operator)      — near-black, denser, mono
 * Both are expressed here. Base values first, semantic aliases
 * second. The webapp-compatible aliases (--bg-base, --accent,
 * --status-*) let UI-kit recreations consume the real product
 * class system unchanged.
