/* ritz — "Console" theme.
   A launch console for your launch console: terminal-chrome panels, an indigo
   accent, monospace command headers set against a warm serif body face. Committed to
   dark-only (this is a CRT, not a color-scheme toggle) — color-scheme: dark below tells
   browsers not to fight it with forced light-mode form chrome.

   Accent/scope palette is kept in sync with the real app's Graphite theme
   (crates/ritz-app/src/theme.rs) — same ACCENT for brand + links (the app has no
   separate link color, so neither does this site), same scope chip hexes, same
   warning color reserved for the warning role only. */
