/* Kimma platform demo. Design note: follows docs/design/DESIGN.md ("The Quiet Ledger").
   Tokens: white page and cards, #ECECEE hairlines, #FAFAFA wells, ink #0A0A0A, zinc text
   #3F3F46 / #52525B / #71717A; one violet #6E4FF5 (links #5B3CE0) for focus, selection,
   Kimma's own marks and single-series bars. Status = tinted chip + icon + word. Primary = black.
   Type: Geist 11 to 26px (h1 24/600, section 15/600, body 14, UI 13/500, labels 12); Geist Mono
   only for Lean, code, ids and digests; tabular figures everywhere. Radii 8 / 10 / 14 / 999.

   gain their method and verification chips. Motion lives only in the fast-forward runs. */
