/* =============================================================================
   Design System — HAL 9000 SCIENCE · "the ship's science computer"
   =============================================================================
   ONE deep-space-black ground, cold slate consoles, thin glowing rules, and
   ONE signature HAL red — the eye — that means live / computing / alive
   (docs/DESIGN.md is the SSoT). Everything is dark: the whole app is the
   instrument. The reader reads a serif "console readout"; the interface speaks
   a clean techy sans (Geist); the machine speaks mono (JetBrains Mono) — and
   the wordmark is wide-tracked uppercase mono.

   HAL red (#E8331C) is reserved: the eye, active state, computed signal, focus.
   Cold cyan (#35D6E8) is the secondary data accent; amber (#E0A44A) is null /
   caution. Every ak-* class resolves the --color-* / --font-* tokens from the
   @theme block (app/assets/tailwind/application.css).
