/* Login page — 2026-11-09 founder pick "photo-glass1" (mockups/login-demos/photo-glass1.html):
 * a soft, slightly blurred classroom photo, a light teal wash, the words on the left and a glass login card.
 * The old sunrise scene is kept in mockups/login-old/. CSP: every style lives here, no inline style="".
 * Every id / class the login script uses is unchanged (.tabs button[aria-selected], .lang button[aria-pressed],
 * .msg / .msg.ok, .school, #toasts …). Text colours meet 4.5:1 (S11 WCAG rule), touch targets 44 px. */
