/* ===========================================================================
   Theme — Report 2026-07, "A Proactive Strategy for Mitigating the
   Twenty-First-Century Polycrisis"

   Aesthetic: classical journal. Warm cream, deep burgundy, a contrasting
   teal, and a high-contrast didone for display. The distinguishing move is
   compositional rather than chromatic: this is the first report in the
   series with a centred, symmetric masthead — a title page rather than a
   left-aligned banner.

   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.

   extra weight and a slightly larger size in this theme. */
