/* ===========================================================================
   Theme — Report 2026-17, "Navigating the Transition"

   Aesthetic: navigation chart. The report argues that the exposure cannot be
   forecast, only steered, so the masthead is a chart-paper field with rhumb
   lines radiating from a point (a repeating-conic-gradient — the first
   angular motif in the series) and section headings sit on a bearing line
   with a brass diamond marker. Bodoni Moda gives the engraved chart-title
   look, Outfit reads, Spline Sans Mono carries the figures.

   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.
