/* ==========================================================================
   Louisville Biz Events - site.css
   Civic print calendar. Flat surfaces, hairline rules, no gradients,
   no shadows, no centered hero. Mobile first, single stylesheet, no framework.

   Class names inside the two SSR regions (.event-card, .day-card,
   .series-entry, .chip-*) are generated by the build. js/app.js emits the same
   names on re-render, so every rule below serves both the server-rendered
   paint and the client re-render. Do not rename one without the other.

   Contrast ratios below are measured against the surface named in each comment
   (sRGB relative luminance, WCAG 2.x formula). Same convention wilmington-web-guy
   uses: the accessibility math lives next to the token, not in a separate doc.
