   Theme — Report 2026-42, "Wet-Bulb Temperatures and the Emerging Geography
   of Unsurvivable Heat"

   Aesthetic: mercury skyline. The masthead is a skyline of thermometer
   columns, one for each of the 161 sites analysed, sorted by the highest
   hourly wet-bulb temperature each reached in 2024 and filled on a
   teal-to-crimson ramp. Two horizontal lines cross it: the 30.5 °C limit
   measured in humid heat for young adults and the 35 °C theoretical
   ceiling. The gap between the tallest columns and those lines is the story
   (inline SVG data URI) on a deep petrol field. Below it the page is cool
   condensation-grey paper. The measured limit is orange, the theoretical
   ceiling crimson, warming levels run from teal to violet, and every h2
   opens with a small wick thermometer. Antonio for display, Sarabun for
   prose, Google Sans Code for figures.

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