/* Northstar ID design system (DESIGN 8.1, ENTSCHEIDUNGEN I1/I4/I5/K1).
   Binding: white frosted glass, border-radius 0 everywhere, auth panel on
   the right, full-screen nature photos. Dark mode follows the system unless
   the viewer chose light or dark (data-theme on <html>, see the dark tokens).
   No inline styles anywhere (CSP) – everything lives here.

   Contrast: every text/UI token is chosen for WCAG AA on the panel
   surfaces. Panels are frosted glass at 72 % (light and dark, user
   request for more transparency) with a 30px blur; text and muted text keep
   AA even over a pure black/white photo pixel (muted tokens chosen for that),
   the blur averages the photo so real backgrounds stay near the surface range
   the accent tokens are checked against (internal/platform/theme).

   Accent: the --accent* tokens below are the SkyKopf default. A user's own
   accent colour is applied by /theme/v<N>/accent-<rrggbb>.css (generated by
   internal/platform/theme, linked after this file), which overrides exactly
   these custom properties per colour scheme. Components must only use the
   tokens, never raw accent colours. */
