/* =========================================================================
   Daphne public site — TIDE design system, IRIS mode (Sentinel six-mode
   system, S-0176; token source of truth = pwa/styles/modes.tokens.json —
   consumed, never forked. Layout/motion lineage: docs/artifacts/daphne-hud.html,
   D-71 canon).
   Tier grammar (IRIS): public = violet accent · sensitive gold ·
   never-leaves-LAN teal (violet is the identity accent here) ·
   red = deny/alarm ONLY.
   Fonts: Space Grotesk (readouts) + Lora (voice), self-hosted from
   assets/fonts/ (OFL, S-0176 static-asset annotation) with system
   fallbacks — no network fetch, ever (local-first posture).
   Label grammar per the ratified Sentinel reference
   (docs/artifacts/design-handoff-hub-identity/): micro-labels 7–10px,
   600 weight, .2–.3em tracking, uppercase, dim; wordmark tracked .42em;
   hairlines = accent at ~.13 alpha.
   Material-style elevation is expressed with layered surfaces + soft
   shadows on the near-black Tide background.
