/* THE DOCUMENT PAGE (#2477). Design of record: screen `docpage` in docs/design/platform/email-platform-mock.html
   (approved 26 Sep 2026). The first three blocks are that prototype's canonical token head, verbatim; the
   component rules are the prototype's, with each of its inline style="…" attributes turned into a class,
   because the CSP (staticwebapp.config.json) allows no inline style. */

/* Tokens mirrored from stoktake/apps/web/_shared/styles/_global.scss. Three theme states:
   bare :root is light, [data-theme="dark"] is the explicit choice, and the media query
   covers the un-stamped default. No literal colour is defined only inside a dark block. */
