/* /diablo/site.css
 * Dark "infernal" theme for the Diablo II bot showcase page.
 *
 * Theming notes for future agents:
 *   - We DO NOT use /shared/css/routes-base.css here. The shared CSS targets
 *     light-themed business landing pages and clashes with the dark aesthetic.
 *     A self-contained stylesheet is intentional.
 *   - Color palette is pulled from Diablo II's UI (oxblood reds, parchment
 *     gold on charcoal). Keep the palette CSS variables at the top so it's
 *     easy to retheme.
 *   - The layout is a single vertical document. No sticky nav, no app shell —
 *     this page is a showcase, not a SaaS product surface.
