   auth.css — anonymous (sign-in) surfaces
   Loaded ONLY by templates/accounts/{login,forgot_password,reset_password,
   accept_invitation}.html and legacy_clinics/invite_accept.html, after
   platinum.css.

   2026-09-23 — rebuilt against the public site's sign-in page
   (platinumsystem.com/accounts/login/), which is the reference every
   anonymous surface follows:

   · The shell is BRAND-LOCKED. The pitch is navy and the form side is the
     site's ice paper whatever the visitor's OS theme says. The app theme
     (system / dark) is a signed-in preference — an anonymous page has no
     toggle, and under a dark OS the old page rendered a washed-out sky CTA
     on the void. The lock is done by re-declaring the tokens on `.pl-anon`:
     custom properties resolve per element, so every `var(--pl-*)` and
     `var(--bs-*)` under the shell — Bootstrap's .form-control and
     .form-check-input included — picks up the light values without any
     `[data-theme]` selector fight.
   · Both panels centre their content vertically. The pitch carries three
     feature TILES (icon + title + line), the site's pattern, instead of a
     bullet list and a chip strip.
   · The form title is DM Serif Display, the CTA is the site's coral-dark
     button (#c94a2d — white on the brighter coral fails AA), and the page
     ends with the site's "Back to home" row.

   Everything is namespaced `.pl-anon__*`. The lock only uses platinum.css
   tokens that do NOT move in dark mode (neutral ramp, primary scale, brand
   inks, coral / sky / sage solids), plus the light status literals that
   the dark block would otherwise swap for translucent washes.
