/* starnet-kit.css — the STATION LOOK for plugin windows (plugin extensions phase 1, 2026-09-29).

   Injected at the top of every plugin page by the sidecar (/plugin-ui/ route). Everything here is copied from the
   station's own GLASS recipes (frontend/css/glass-demo.css + style.css tokens) — a plugin built from these classes
   looks like it shipped with StarNet, and repaints with the station when the Commander changes the phosphor.

   · Tokens: the defaults below are the amber reference build. starnet-kit.js overwrites them on :root with the
     station's LIVE computed values the moment the window opens and on every theme change.
   · Everything sits in `@layer starnet`, the lowest layer: any CSS the plugin author writes (unlayered) wins, with
     no !important and no specificity fights. The kit is the default, never a cage.
   · Matte glass, no glow. No control is ever left in the browser's own white paint (the station's standing law).
