/* ============================================================================
   Foluka waitlist: one stylesheet for every page of foluka.com's waitlist site.

   The colours, radii, type and motion are the product's own tokens
   (src/design/tokens.css), copied here because this site is deployed on its own
   and cannot read the app's files. waitlist/test/site.test.js compares every
   value below with tokens.css, so the two cannot drift apart unseen.

   The rules this page keeps, as the app does: nothing a person must read is
   under 12px; every button, field and standalone link is at least 44px tall;
   one focus ring; motion is silent and stops under "reduce motion"; light and
   dark follow the visitor's system.
