/* =========================================================================
   GianOS — Terminal app styles
   Committed dark in-fiction palette (this app only; not global dark mode).
   Deep phosphor terminal aesthetic: green/amber on near-black, Geist Mono.
   All colors OKLCH only. Scoped under .app-screen[data-app=terminal] and
   body[data-app=terminal] overrides for statusbar + app-head.

   Contrast: --term-text on --term-bg ≥ 4.5:1 (verified: ~7.8:1 at these
   oklch values). --term-amber on --term-bg ≥ 4.5:1 (~5.1:1).

   These tokens are fixed — they do not follow --seed (Terminal's art direction
   is deliberately immune to the theme toy, per plan).
