/* ===========================================================================
   Theme — Report 2026-06, "Climate Adaptation as Infrastructure"

   Aesthetic: engineering drawing. A pale blue-grey ground with a faint
   blueprint grid behind the masthead and the annotation panels, deep
   drawing-blue structure, safety orange for the binding constraint, and a
   slab serif — the first in the series — for display.

   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.
