/* Log in ("/" and /login), "get a login link", "choose your password" and
   "change your password" (Pau, 2026-10-22, the "mix" design): a thin
   blue-to-pink line on top, the ScaledOn elephant alone above a white card
   with a gradient top edge and a soft brand glow, and far behind, a faint,
   blurred glimpse of report cards that fades out around the card. Static:
   nothing moves. Tokens are report.css's; keep them in step.
   Used by public/login.html, public/set-password/index.html,
   public/pwd-reset/index.html and functions/_shared/login-pages.js. */
