/* ============================================================
   EvalQA — theme.css
   THE single source of truth for design tokens, typography and shared
   components. Nothing here is duplicated in a page: if a page needs a colour,
   a size or a spacing value, it comes from a token or a class defined here.
   Marketing-layout components (hero, bands, pricing cards…) live in
   landing.css and are loaded only by pages that use them.

   Theme
   -----
   The site is LIGHT ONLY. Light tokens live on :root and apply to everyone:
   the OS dark preference is deliberately not consulted, no toggle is rendered,
   and no stored preference is read, so there is nothing to flash on first
   paint. A dark palette is kept dormant under :root[data-theme="dark"]; the
   single switch that would bring it back is EVQ_THEME_ALLOW_DARK in _theme.php.

   Contrast
   --------
   Every text token is verified against every surface it can sit on. Worst
   ratio: light 5.74:1, dark 4.66:1 — both clear of the WCAG AA floor of 4.5:1
   for body text. Do not add a colour here without checking it.
