/* Scouncil — the shared stylesheet of the student site (design phase, 2026-09).
   Two visual languages, one family (design/mocks/deliverables/DIRECTION.md):
     html.lang-a  the sign-in shell: white, 32px grid, gold, doodle corners
                  (login, enroll, recover, lock)
     html.lang-b  the signed-in pages: paper, ink, five pastels, no gold
   Everything a page needs that is not page-specific lives here: tokens, type,
   buttons, cards, pills, notices, form fields, PIN cells, the loader, the top
   bar and account menu, the rail layout, the footer, keyframes, reduced motion.
   No inline styles anywhere (CSP): dynamic numbers are set through the CSSOM. */
