   DateSpark stylesheet
   Direction: 2026 clean minimalist. The dataset is the design: a full-width
   ledger of 120 hairline-divided rows, mono index numbers and metadata,
   soft serif titles for warmth, one carmine accent used with intent.
   Type: Fraunces (display) + Hanken Grotesk (text) + DM Mono (metadata).
   Flat and sharp: 1px rules, square corners, zero shadows, motion under
   160ms ease-out or none at all.
