/*
 * Certificates — the three attendee-facing page types, in the site's
 * black-and-white editorial voice:
 *   1. the share page   (/c/<CODE>)               .cert-share
 *   2. the claim pages  (/certificates/, /certificates/<event>/)
 *   3. the verify page  (/certificates/verify/)
 *
 * Palette, type, buttons (.btn/.btn-ink/.btn-outline) and the page frame come
 * from site-tokens.css + landing.css + subpage.css. This file adds ONLY the
 * certificate-specific objects and consumes custom properties exclusively —
 * no literal colours, so the whole surface follows a token change.
