/* Circuit reconnection toast + overlay (see js/circuit-reconnect.js and App.razor).
   Plain CSS with a self-contained spinner — no icon-font dependency — so it renders
   correctly on every page (including those that don't load Bootstrap Icons) and while
   the Blazor circuit is down. Bootstrap CSS variables are used where available, with
   light-theme fallbacks, so the toast follows the active data-bs-theme. */
