/* F7less — Swiss Technical Design System (Canonical Common Stylesheet)
 *
 * Neo-grotesque typography on a strict grid, hairline rules doing the
 * structural work, square corners, and no ornament.
 *
 * Palette is anchored by the logo's three-bar cyan gradient:
 *   #0e7490 (5.36:1 on white) anchors the light scheme.
 *   #22d3ee (10.92:1 on near-black) anchors the dark scheme.
 *
 * Status colours follow the measured Swiss Technical scale:
 *   #0f6d43 / #34d399 (ok)
 *   #92400e / #fbbf24 (warn)
 *   #b42318 / #f87171 (danger)
