/* ============================================================
   Shared app stylesheet
   ------------------------------------------------------------
   The one copy of the palette, element resets and component
   classes. Linked by the app page (Decarbonisation Platform.html)
   AND by every harness/_harness_*.html, which used to paste their
   own copies — and had drifted onto the pre-brand-redesign palette,
   so a harness no longer showed what the app showed.

   Class-based rules live here rather than in inline styles because
   they need selectors React can't express: :hover, :focus-visible,
   position: sticky pairs, @media and @container.

   Paths are relative to THIS file (model/), hence ../assets/… —
   that resolves the same whether the page sits at the project root
   or in harness/.

   The IBM Plex Mono webfont stays a <link> in each page: an @import
   here would block the first paint behind a second round-trip.
