/* Lumo UI: shadcn/ui's design language (New York style, zinc base), written as
   plain CSS on VS Code's theme so it runs in a webview with no build and no
   network. One accent, the hero's colour (--hero, --hero-foreground), used
   sparingly: the primary button, focus rings, progress, the current account.

   Tokens follow shadcn's names. Components are .ui-* classes. Icons are Lucide
   paths (24 viewBox, stroke 2) inlined as SVG. */
