/* Railyard API reference — self-contained, same-origin stylesheet.
   No @import, no CDN. Fully CSP-safe under style-src 'self' / font-src 'self'.

   This page is hand-built static HTML rather than part of the React app, so it can't share
   src/index.css. The palette below therefore MIRRORS the app's design tokens by hand — keep it in
   step with :root in frontend/src/index.css if those change. Railyard is a single dark theme, so
   there is deliberately no prefers-color-scheme branch: this page used to go white in light mode,
   which made it the only surface that didn't look like the product. */

/* IBM Plex Sans, the app's typeface. Vite content-hashes the fontsource files it bundles, so a
   static page can't reference those; these are copies under public/ (served verbatim, stable URLs).
