/* =====================================================================================
 * app.css — web-guardian, built against the REAL Claude Design export ("Ember"), landed
 * 2026-07-12. Imports tokens.css + components.css directly and uses their `.ra-*` classes as the
 * primary building blocks; only structural/page-scaffolding CSS lives here.
 *
 * Hard rules from design/README.md this file (and ui.js) must uphold — see the handoff for the
 * two flagged conflicts (pre-alert / check-in "PIN-gated" vs the binding no-PIN state machine):
 *   1. Green = safe/resolved ONLY. Armed = amber. Live alert = red. Degraded = amber hazard.
 *   2. #10/#11 (PIN entry, cancelled/resolved confirmation) are pixel-identical for safe & duress.
 *   3. Status is never color-alone — every state pairs a glyph + words (components.css bakes
 *      this into .ra-row / .ra-chip / .ra-banner-* already).
 *   4. Touch floors: 56px interactive, 64px primary, 84px critical (SOS / I'm OK), 76px PIN keys
 *      — all from --hit-* tokens, applied via the .ra-btn / .ra-key modifier classes.
