The \"\u00D7\" standard \u2014 one delegated `document` click listener for every\n *    [data-action=\"dismiss\"] control. On click:\n *      - finds the closest [data-overlay] ancestor. A click with no such\n *        ancestor is a silent no-op \u2014 some overlays intentionally never\n *        carry [data-overlay] because they own a bespoke show/hide idiom\n *        this generic handler can't safely drive (the mutation-queue\n *        toast's slide transition \u2014 templates/includes/_toast_banner.html\n *        \u2014 and #offmap-banner's hidden/flex dual toggle \u2014 see\n *        public/templates/public/map.html); their own JS keeps binding\n *        its own dismiss listener directly.\n *      - hides it using the idiom the element declares:\n *        `data-overlay-hide=\"class\"` toggles the Tailwind `hidden` CLASS\n *        (every shell-chrome banner/toast/modal); the default toggles the\n *        HTML5 `hidden` ATTRIBUTE (map-internal overlays and sheets \u2014\n *        #map-help-overlay, #favourite-sheet, #report-sheet).\n *        Never flips which idiom an element uses.\n *      - optionally persists a localStorage flag via\n *        `data-overlay-persist=\"key=value\"`.\n *      - dispatches a bubbling `overlay:dismissed` CustomEvent\n *        (`detail.overlay` = the element) so the owning module can run\n *        teardown beyond hide (map_sheet.js deactivates the place-picker\n *        and clears the sheet's content for both map sheets, and drops the\n *        shared toast's auto-dismiss timer; map_help.js sets aria-hidden\n *        and restores focus) without binding its own\n *        \u00D7-click listener.\n *\n * 2. A shared toast auto-dismiss controller \u2014 any element carrying\n *    `data-toast-timeout=\"<ms>\"` (an opt-in on templates/includes/_toast.html)\n *    is watched for becoming visible and hidden again that many ms later,\n *    via the same idiom-aware hide as above. The three offline toasts in\n *    public/partials/_map_embed.html opt in at 6000ms; a toast whose text\n *    is rewritten between reveals (map_sheet.js's #map-sheet-toast) runs\n *    its own timer instead, since a text change fires no mutation the\n *    observer below watches for and so would not re-arm this one.\n */\n\n(function overlayDismissInit() {\n  'use strict';\n\n  /**\n   * Hide `el` using the idiom it declares.\n   * @param {HTMLElement} el\n   */\n  function hideOverlay(el) {\n    if (el.dataset.overlayHide === 'class') {\n      el.classList.add('hidden');\n    } else {\n      el.setAttribute('hidden', '');\n    }\n  }\n\n  /**\n   * Whether `el` is currently hidden, per the idiom it declares.\n   * @param {HTMLElement} el\n   * @returns {boolean}\n   */\n  function isOverlayHidden(el) {\n    return el.dataset.overlayHide === 'class'\n      ? el.classList.contains('hidden')\n      : el.hasAttribute('hidden');\n  }\n\n  /**\n   * Persist a `data-overlay-persist=\"key=value\"` declaration to\n   * localStorage, tolerating storage errors (private mode / full quota) \u2014\n   * matching every other localStorage write in this codebase\n   * (map_tour_offer.js, map_help.js, pwa_install.js).\n   * @param {string} declaration\n   */\n  function persist(declaration) {\n    const eq = declaration.indexOf('=');\n    if (eq < 0) return;\n    const key = declaration.slice(0, eq);\n    const value = declaration.slice(eq + 1);\n    try {\n      localStorage.setItem(key, value);\n    } catch (_err) {\n      // Ignore \u2014 this session's dismissed state simply doesn't persist.\n    }\n  }\n\n  document.addEventListener('click', function (event) {\n    const target = /** @type {HTMLElement} */ (event.target);\n    if (!target || !target.closest) return;\n    const trigger = target.closest('[data-action=\"dismiss\"]');\n    if (!trigger) return;\n    const overlay = /** @type {HTMLElement|null} */ (\n      trigger.closest('[data-overlay]')\n    );\n    if (!overlay) return;\n\n    hideOverlay(overlay);\n    if (overlay.dataset.overlayPersist) persist(overlay.dataset.overlayPersist);\n\n    overlay.dispatchEvent(\n      new CustomEvent('overlay:dismissed', {\n        bubbles: true,\n        detail: { overlay: overlay },\n      }),\n    );\n  });\n\n  // ---------------------------------------------------------------------\n  // Shared toast auto-dismiss controller.\n  // ---------------------------------------------------------------------\n\n  /** @type {WeakMap<Element, number>} */\n  const timers = new WeakMap();\n\n  /**\n   * (Re)arm or clear a toast's auto-dismiss timer based on its current\n   * visibility.
