/* ===========================================================================
   Theme — Report 2026-22, "The Polycrisis Century"

   Aesthetic: heat map. A light analytical dashboard — the counterpart to the
   dark operations dashboard of 2026-21 — whose centrepiece is the stress
   calendar. The sequential ramp used in the calendar (sand to oxblood) also
   forms the masthead's closing strip and every "hot" accent, so the page
   reads in the same colour scale as its data. Indigo marks chronic pressures.
   Schibsted Grotesk for display, Atkinson Hyperlegible — designed for
   legibility — for text and its mono for figures.

   Loaded after report.css; report.js reads these tokens for chart colours.
