/* Registration page and confirmation page — mobile-first. ROUND 4, 2026-08-28.
   Michael asked for a ground-up redesign with full flexibility (taste-skill
   pass), which supersedes the 2026-08-25 round-3 lock. What did NOT move:
   every copy string (still pinned by tools/check_page_copy.py), the form DOM
   contract with register.js and the server, the disclaimer prominence rules,
   and the decisions that survived from round 3 on purpose:

   - the session facts live INSIDE the signup card (Michael, 2026-08-25)
   - the gold word in the headline
   - the flat navy ground with one quiet fractal-noise grain, no washes
   - the top bar is WHITE so it reads as its own plane
   - a named, pictured host

   What is new in round 4: Bricolage Grotesque display type over Inter body,
   both self-hosted from /assets/fonts (no Google CDN request); the session
   header inside the card goes navy so the card reads as a ticket; the covers
   list becomes a five-cell bento with one navy and one gold-tinted cell; the
   host photo gets a gold offset panel; entrance and scroll-reveal motion,
   fully gated behind prefers-reduced-motion.

   Radius system, one rule everywhere: containers 18px, controls 12px,
   chips/badges full pill.

   Senior floors, unchanged: 18px body minimum (17px wordmark is the one
   exception), labels above fields, 48px+ full-width CTA, one column on
   mobile, contrast measured not eyeballed (tools/contrast notes in log). */
