/* API Library UI stylesheet (task 5.1).
   Ports demo-match's STYLE tokens and the gate rules (.overlay/.modal/.field/.btn/.btn.primary/
   .btn.ghost/.err) verbatim, then adds the app chrome this catalog needs: the 1,200px content
   column, the responsive table pattern, method badges, code blocks, and the light/dark variants
   (demo-match is light-only; the dark values are the plan's: canvas #0f172a, surface #111c33,
   text #e5edff, border #26324a, brand unchanged).
   Deviation from demo-match: no Google Fonts @import — the pages ship CSP style-src 'self',
   which blocks cross-origin stylesheet loads, so Inter resolves from the system when installed. */
