/* ============================================================================
   INGSOC design system — shared foundation for every surface
   (auth · public · cabinet · admin). Loaded first in all four layouts.

   Concept: total surveillance as backdrop (concrete grey-blue, black
   telescreen, party red) pierced by the warm amber lamp of freedom — the
   VPN as quiet resistance. Two themes: light = Ministry daylight,
   dark = telescreen night. All assets self-hosted (no external origins).
