/* ===========================================================================
   Theme — Report 2026-30, "The Infrastructure of Sustainable Economic
   Convergence"

   Aesthetic: the transit map. The report treats four infrastructures as
   lines that carry an economy towards the frontier, so the page borrows the
   grammar of a metro diagram: the masthead carries four coloured lines with
   45-degree bends meeting at an interchange (inline SVG data URI) over a
   night-slate field; every h2 opens with a station roundel in its gate's
   colour on a line rule; panels are white cards with a coloured line tab.
   Each gate keeps one colour throughout: power amber, logistics blue,
   cooling teal, connectivity magenta. Big Shoulders Display for display,
   Rethink Sans for prose, Noto Sans Mono for figures.

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