   Headings are painted with the fixed brand ink

   for that only ever covered .app-content - the signed-in shell.
   Public pages (sign in, register, password reset, landing) sit

   a near-black surface and became unreadable.

   UI-09 - Selectable colour palettes

   Only six tokens are redefined per palette. Everything else in
   this stylesheet derives from them, which is why a palette is a
   handful of declarations rather than a second stylesheet.

   Two roles, two accessibility rules:

     --theme-accent is decorative - low-alpha washes, glows, hover
     tints. Nothing is legible only because of it, so it is chosen
     for appearance and pinned to the same perceptual lightness as
     the default blue.

     --theme-accent-strong carries text and interactive state, and
     is solved numerically against the surface it sits on: at least
     4.5:1 (WCAG AA) in light mode, and matched to the existing
     design's brightness in dark mode, which is well beyond AA.

   Placed at the end of the file deliberately. The palette
   selectors and html[data-theme="dark"] have equal specificity in
   the light case, so source order decides.
