/* ===========================================================================
   Theme — Report 2026-27, "The Pollution–Climate Risk Nexus"

   Aesthetic: feedback loop. The report is about cycles that feed themselves,
   so the masthead carries large circular arrows drawn as an inline SVG data
   URI (the first drawn — rather than gradient — masthead motif in the series),
   over a deep teal field; every h2 opens with a small cycle mark (↻) in the
   accent and sits on a rule that ends in an arrowhead. Each domain keeps one
   colour throughout: climate red, pollution ochre, health rose, ecosystems
   green, development indigo. Urbanist for display, Onest for prose, Ubuntu
   Sans Mono for figures.

   Loaded after report.css; report.js reads these tokens for chart colours,
   and charts.js reads the --d-* tokens so no hex lives in the script.
