/* ============================================================
   LEDGER — the site-wide material system.
   Extracted from jury-sim.html (v9a Ledger, PR #94) so every
   page shares the same fonts, palette, and register:
   editorial serif display (Source Serif 4) + Inter body/data,
   paper white, warm neutrals, bronze accent, hairline rules.
   No gradients, no emoji, no stock hexes.

   Load order: after variables.css / base.css / components/*.css.
   The :root block below re-maps the legacy variables, so most
   component CSS inherits the new material without edits.
   jury-sim.html keeps its own inline copy of this system.
