/* ═══════════════════════════════════════════════════════════════════════════
   Shared stylesheet for the AWS for Healthcare event sites.

   ONE canonical copy lives here in the repo. `publish.sh site <name>` copies
   it to each site's bucket as /event.css, so every site serves it
   SAME-ORIGIN.

   That same-origin requirement is not cosmetic: CloudFrontSigner does not
   authenticate cross-origin resource requests made from HTML tags. A
   <link> pointing at a stylesheet on another Midway-gated domain would be
   refused, and the page would render unstyled. Never reference this file
   across hostnames.

   Covers: event landing pages and their /outcomes pages.
