   bk33cm.click — bk33cm-palette-3ec545.css
   Mobile-first base styles. Design direction:
   - palette: #B8860B (deep gold) / #FFB347 (amber) / #F8F9FA (paper) / #2C2C2C (ink bg)
   - geometric headings + neutral body, mixed corner radii, compact layers
   - game card form: horizontal icon + name bar
   - motion budget: route-sheet slide-in + light card lift only
   All classes and custom properties use the uiec545- prefix.
