/* ==========================================================================
   cedra.css - shared stylesheet for the Cedra draft site (v1, 2026-10-05)
   Based on proposal/cedra.css (v0). Changes in v1:
   - light theme only (dark tokens and theme toggle removed);
   - no hero gradient, no "Mac window" chrome: code and previews use .figure;
   - pills (.status) only for statuses: In development / Planned / Built in;
     section eyebrows use .label (no background);
   - new section patterns from research/site-review/ui-designer.md:
     spec rows (.rows + .split-grid), stat strip (.stats), spend ledger (.ledger);
   - two-step early access form, privacy page prose, mobile fixes (44px targets,
     no horizontal scroll at 390px, code scroll hint).
   Layers: reset < tokens < base < layout < components < utilities.
   Unlayered page styles win over all layers.
