/* observ.css — ON1 observability hub.
 *
 * Aesthetic flavour: "MISSION-CONTROL / CONTROL-ROOM" — a flight-ops
 * annunciator console. Distinct from every prior surface flavour
 * (cyberpunk/dashboard/newspaper/schematic/sparkline/editorial/
 * river-delta/ledger/observatory). The motifs:
 *   - deep console graphite + a thin amber rule "instrument bezel"
 *   - status lamps (annunciator tiles) that glow GO / NO-GO / STALE
 *   - segmented mono readouts, console-strip header, plate-glass cards
 *
 * Three project fonts (loaded by observ.html):
 *   Chakra Petch   → display headlines / console plate marks
 *   Familjen Grotesk → body / sans
 *   IBM Plex Mono  → telemetry numerals + technical labels
 *
 * Palette verified for WCAG AA (>=4.5:1 body text). Worst case body
 * pair: --ink-1 (#c3d0d8) on --bg-1 (#12181d) ≈ 9.6:1. Muted label
 * --ink-2 (#9fb1bb) on --bg-1 ≈ 6.7:1. Both clear AA comfortably.
