/* Relim site. One stylesheet, no build step, no webfont, no third-party asset,
   no JavaScript anywhere on the site — /privacy asserts all four, so each is a
   claim this file has to keep true.

   Every colour below is a token from the app's own palette,
   app/relim-flutter/lib/core/theme/colors.dart, so the site and the product are
   the same object. Two deliberate departures, both because a phone glyph and a
   web paragraph are graded against different WCAG thresholds:

     --on-accent  the app's `onAccent` is white in both themes, which is 3.69:1
                  on the dark violet — enough for the FAB glyph it is used for
                  (1.4.11, 3:1) and not enough for button TEXT (1.4.3, 4.5:1).
                  Dark therefore sets ink on violet, 5.20:1.
     --muted      never placed on `bgHover`/`--raise` in the light theme, where
                  it measures 4.26:1. Text surfaces are `--ink` and `--panel`.

   Measured ratios for every pair in use are listed in web/README.md. */
