/**
 * THE CONTINUITY BUREAU — site stylesheet
 * ------------------------------------------------------------------
 * Register: Swiss-grid civic document meets terminal. Carved, not typed.
 * Palette: near-black, bone/paper, ONE accent — oxide red.
 * No gradients-for-gradients'-sake. No neon. No crypto aesthetics.
 *
 * Contract notes inherited from hard-won bugs across drooly repos:
 *  - never a bare `1fr` in grid-template-columns (that is
 *    minmax(auto,1fr) and blows out narrow viewports) — always
 *    minmax(0, 1fr).
 *  - coarse-pointer rules are or-shaped, never (pointer: coarse) alone.
 *  - every tappable clears 44px on BOTH axes.
 *  - system font stack only; zero external calls of any kind.
