/* ===========================================================================
   Theme — Report 2026-03, "Climate Adaptation and Development Convergence"

   Aesthetic: quantitative working paper. Cool white ground, deep indigo
   structure, a single rose signal colour, and numerals set in mono so the
   figures read as data rather than display type. Section headings are ruled
   from above rather than underlined (2026-01) or barred from the left
   (2026-02), and the masthead runs on an indigo spine instead of a block.

   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.
