/* ===========================================================================
   Theme — Report 2026-04, "Breaking the Pollution–Poverty–Climate Nexus"

   Aesthetic: dark editorial. The first report in the series to run dark all
   the way through rather than only in the masthead — a near-black ground,
   amber structure, coral for harm, and Fraunces / Figtree / Space Mono.

   Long-form on a dark ground needs deliberate handling: body copy is set on
   a desaturated blue-grey rather than pure black, at a slightly larger size
   and looser leading than the light themes, and text colours are held above
   a 9:1 contrast ratio. Chart palettes are lightened accordingly, since
   report.js reads them from these tokens.
