/* ==========================================================================
   SIGNAL · design system for The Apostates
   Voice: forensic research lab. Every claim carries a provenance chip that
   resolves to a source entry; every source carries a verification state.

   Families (spec cap = 3): Space Grotesk (display/UI), Geist (reading),
   Noto Naskh Arabic (scripture). Mono metadata uses the platform mono
   (SF Mono / Cascadia / Menlo) so no 4th webfont is downloaded.

   Color: off-black #0b0d0c field, one emerald accent. Light mode is a cool
   lab-paper (#f3f4f1). All pairs checked to WCAG AA.

   Type scale (minor third, fluid): 13 / 17 / 20 / 24-32 / 32-52 / 48-136px.
   Rhythm: 17px body on a 28px line; vertical spacing in 7px multiples
   (--s-*) so blocks land on the baseline grid.

   Grid: 12 columns, max 1280px, 24px gutters, 16-48px side padding.
   Radius: one token, --r: 3px, used on every rounded surface.
