   koordinat-pages.css — Subside re-skin til det GODKENDTE index-design
   (dk/mockup/index-fable.html): warm cream, koordinat-grid, én gradient,
   sektions-grammatik, emil-detaljer.

   ⚠️ MÅ KUN loades af subsiderne (height_system / transformation / csv /
   dwg_dxf / shape) — EFTER /shared/css/koordinat.css.
   ALDRIG i tool.html (tool.html bruger koordinat.css + tool.css).

   Strategi:
   1) Token-remap (kun light — koordinat.css' [data-theme="dark"] bevares)
   2) Komponent-overrides oven på koordinat.css (samme mønster som tool.css)
