/* ============================================================================
   Uni Login — shipped default look for the bare front-end auth page
   (login · lost-password · reset · register).

   A neutral, unbranded but fully designed login: glass-ish card, greyscale
   palette, saved light/dark, a site-name text wordmark (no logo), flat
   background. Self-contained — depends on NOTHING else (its own tokens, fonts,
   toggle). Loaded by login-page.php only when UNI_LOGIN_DEFAULT_STYLE is on.

   Rebrand contract: a site restyles by REDEFINING the `--ul-*` tokens (colours,
   radius, font) — the component rules never need touching. Or a site can ship
   its own complete design and set UNI_LOGIN_DEFAULT_STYLE=0 to suppress this.

   All colour tokens are neutral greys (chroma ~0); the accent is a restrained
   slate-graphite. Status colours (ok/crit) stay saturated — they are functional
   feedback, not branding.
