/* Design tokens ported from ../../assets/app.css (the private-practice
   FollowOps app) — same restrained neutral black/white/gray structure,
   6px radius, soft pastel status triples, bordered "ghost" controls with
   one bold primary action per view. Deliberately copied rather than
   `@import`ed: this app deploys to its own subdomain/docroot with no
   runtime dependency on the parent app's assets (same reasoning as
   ../../recall/assets/recall.css).

   Indigo accent: --primary swaps from the practice app's teal-blue and
   recall's clay/bronze to indigo (#4338ca — WCAG contrast ~8.6:1 against
   white). Third product under the FollowOps umbrella, third distinct
   accent — lets anyone glance at a screenshot and tell which deployment
   they're looking at, while keeping the same quiet, mostly-neutral
   visual language as both sibling apps. */
