/* =============================================================
   Westwood Works — "WERKSTATT" theme
   -------------------------------------------------------------
   Newspaper-plain studio look: white page, near-black ink,
   one forest-green accent, deep-green CTA bands. DM Sans for
   everything visible, DM Mono for labels / meta / code.
   Structure comes from rules and whitespace, not boxes.

   This is the site's only theme. Tokens live on :root (no
   [data-theme] scoping); it overrides the visual layer of
   foundation.css, which still owns reset, grid, the CSS-only
   nav toggle, responsiveness and a11y.
