/* Dèanta marketing site — hand-written CSS, no build step.
   Layout concept: one long home page made of distinct blocks, Basecamp style.
   Stone-grey page, a dark heather letter band, a tally-book ledger as a paper
   object, a Q&A, then a heather sign-up band.

   Tokens below are a deliberate mix: heather/moss/sand and the stone palette
   are the real app's design tokens (app/assets/tailwind/application.css and
   cairn_controller.js), kept in sync so the product doesn't feel like a
   different brand once someone signs in. ink/night/paper/mute/rule/card/bg
   have no equivalent in the app (it has no dark band, no paper texture) —
   these were designed fresh for this site and are kept as drafted. */
