/* Registration pages, direction A: deep navy + teal (Sree, 16 Oct 2026; decision RG-10). Used by register.html and
   registration.html only; mock: register-redesign-mocks.html, audit: docs/specs/registration-ui-audit.md.
   Navy for actions, teal for selection and progress, no violet on any control (violet stays in the BioAsia logo).
   System: 8px spacing (--s1..--s8), one type scale (12/14/16/20/24/32/40), radii 8 controls / 12 cards / 16 panels.
   All class names start with rx- so they can't collide with site.css (.ic, .org, .card, .badge, .chips, .btn…).
   Tokens are --a-* so the site header and footer keep their own colours. */
