/* ============================================================
   React SPA compat overrides
   ------------------------------------------------------------
   In the original Flask app, admin.html only loads admin.css,
   so there is never a conflict with dashboard.css. In the
   React SPA both stylesheets are loaded concurrently, which
   lets a handful of dashboard.css rules leak onto admin
   selectors and break layout. Neutralize them here — these
   rules do not exist in the original admin.css and exist
   solely to undo that cross-pollution.
   ============================================================ */

/* dashboard.css sets `.stat-card { align-items: flex-start }`, which is
   the right default for the user dashboard but breaks the admin mobile
   layout: when admin flips `flex-direction: column` at ≤480px, that
   cross-axis alignment pushes .stat-content to the left edge even
   though text-align:center is set. Reset to stretch so content spans
   the full card width and its text centers correctly. */

   rules with !important. admin.css already paints matching
   `.stat-icon-pages/orders/messages/trials/courier` variants. The two
   happen to agree on colors today, but if that drifts the admin
   palette wins by explicitly overriding with greater specificity. */
