/* Brain View — styles
   Design world: a private instrument panel for externalized memory — the
   register of a research ledger / observatory console, not a SaaS admin
   template. Restrained color strategy: near-neutral ground, one brass/amber
   accent carrying live state and primary action, category identity carried
   by small deterministic hue dots rather than tinted regions. Dark by
   default (a desk console checked in low evening light is the mandated
   default scene); light is a persisted, equally considered alternate, not
   an afterthought.
   System font stack only (CSP constraint, no external hosts): a serif
   display face for headings (ui-serif → Iowan/Palatino/Georgia) paired with
   system sans for UI text and system mono for keys/ids/timestamps — this
   pairing is what keeps the console from reading as generic sans-everywhere
   dashboard chrome, without loading a single external font file.
