/* ===========================================================================
   Theme — Report 2026-26, "The Polycrisis Bill"

   Aesthetic: the account ledger. The report is an accounting exercise, so the
   page borrows the accountant's paper: the masthead is a ledger sheet — pale
   ruled lines in ledger blue with the red double margin line down the left —
   and every h2 is double-underlined, the bookkeeper's mark for a total.
   Losses are written in red ink, prevention in green, liabilities in ledger
   blue. Old Standard TT (a nineteenth-century book face) for display, Source
   Serif 4 for prose, Cousine (a typewriter-metric mono) for figures.

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