/* Kadensio: marketing site.

   Direction: a ledger. Ruled columns, tabular figures, wide margins, one
   green. Geist and Geist Mono, self-hosted and subset to Latin. Light and
   dark follow the system, and the whole page keeps whichever it is in.

   Shape rule: buttons and inputs are 6px. Everything else is square and is
   separated by hairlines, never by a card, a shadow or a tint.
   Space: a 4px base. 8, 12, 16, 24, 32, 48, 64, 96, 144.
   Accent: --accent on the primary button, links, the hot band and the
   winning side of the comparison. Nowhere else.
   See docs/design/2026-10-04-visual-direction.md. */
