   Parzelle37 — shared stylesheet for every page on parzelle37.app
   ---------------------------------------------------------------------------
   Loaded by: index.html, privacy.html, terms.html and their /en/ counterparts.
   invite.html deliberately keeps its own styles — it is a functional page in
   the sign-up flow, not a marketing page, and is not worth the regression risk.

   Colours live in custom properties so a change happens once, not six times.
   Every text/background pair below was measured against WCAG 2.1 AA with
   scripts/contrast.js — do not introduce a new grey by eye. The three that
   failed on the first pass (#6c8465, #7a8c75) are gone on purpose; --muted
   replaces both at 5.2:1 on the page background and 5.5:1 on white.
