/* ===========================================================================
   Theme — Report 2026-12, "Integrating Adaptation and Mitigation"

   Aesthetic: two threads woven. The report's subject is two agendas that are
   inputs to each other, so the design carries two colours everywhere — a cool
   teal for mitigation and clean supply, a warm ochre for adaptation and
   protection. The masthead is a dark ground with a woven diagonal weft of
   both; section headings sit on a two-thread rule; cards alternate which
   thread caps them. DM Serif Display sets the headings, Karla the argument,
   Overpass Mono the labels.

   Loaded after report.css: tokens first (which also re-colours every chart,
   since report.js reads the palette from them), then the rules that assume
   the default surface.
