/* ===========================================================================
   Theme — Report 2026-18, "Convergence Without Absorption"

   Aesthetic: warp threads. The report is about a workforce that has to be
   carried by something, so the motif is a vertical warp — fine full-height
   lines running down the masthead, and a short warp of vertical strokes under
   each section heading. Ink navy ground, coral for the gap the report is
   about, sage for what absorbs. Young Serif — heavy, slab-edged, single
   weight — sets the display, Plus Jakarta Sans reads, Fragment Mono 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.
