   Sentinela — admin console
   Cold-chain monitoring tool. Campfire conventions: oklch 3-tier tokens,
   dark mode redefined on tier-1 only, logical properties, BEM-like naming.
   Identity: instrument-like, status-forward. Temperature is the color system;
   a cool blue (#5b9dff) is the single interactive accent. Dark mode is a
   near-black blue (the "modern device" palette). No glows, no gradient text.
   Typography: Geist (UI) + Geist Mono (numerics), self-hosted.
