/* ===========================================================================
   Theme — Report 2026-11, "The Economics of Innovation Adoption"

   Aesthetic: curve-paper. A cool notebook ground, teal for the learning
   curve, coral for the shocks, a friendly Fraunces display face and soft
   rounded cards. Consumer report: warmer, rounder, easier on the eye than
   the series' more formal themes.

   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.
