/* CalcIt design system: "Signal, light" (chosen 30 Oct 2026, docs/design/2026-10-30-signal/).
   Loaded by every page AFTER its inline <style>, so these rules win over the page's own at equal
   specificity. Tokens live here; pages only carry page-specific layout.

   Palette: paper #F4F2ED, ink #121315, white panels with #DCD9D2 hairlines, brand green #157249 on
   light and #5BD39A on dark. Chart colours stay inside charts: fuel/margin green #1B8B5A, duty blue #3360FF,
   VAT neutral (ink #121315 on light, paper #EDEBE6 on dark). Alerts use --alert (deep blue, light
   blue on dark). No yellow (WotsItCalled's) and no orange or coral (Eric). Dark is used for weight only: result blocks,
   explainer panels, the footer. Type: Geist for text, Geist Mono for every figure. */
