/*
 * Surface Water Data Portal — the visual world.
 *
 * The one non-obvious decision this file embodies: brand colour and flood
 * status are kept in two token families that must never touch. `--accent-*` is
 * channel blue-green, the dark waterline of Coyote Creek, and it carries links,
 * buttons and identity. `--stage-*` carries how high the water is against a
 * published threshold, and nothing else. On a site whose entire job is telling
 * a resident whether a creek is about to leave its channel, a brand colour that
 * can be read as a warning state is a safety defect, not a taste question.
 *
 * Everything else follows one primitive: the stage column. A vertical bar with
 * the thresholds ruled across it, at every scale from a 30px sparkline in a row
 * to the full-height instrument on a gauge page.
 */

/* ── Faces ─────────────────────────────────────────────────────────────────
 * Display is condensed because gauge plates and topographic sheets are; body
 * is open because it gets read at 3am on a phone; mono is reserved strictly
 * for measured values so a column of readings aligns on the decimal.
