 * Greasy Fork description (paste the block below into the script page on
 * https://greasyfork.org/fr/scripts/576225-claude-plan-usage-limit):
 * -----------------------------------------------------------------------------
 *
 * Monitors the Claude usage page (claude.ai/settings/usage) and sends a
 * notification each time plan consumption crosses a 5 % threshold
 * (5, 10, 15, 20 ... %).
 *
 * ## Features
 *
 * - Auto-detects French and English UI on the Claude page; notification text
 *   follows `navigator.language`.
 * - Uses `GM_notification` with a unique `tag` so a new threshold replaces the
 *   previous notification instead of stacking up.
 * - Stays armed even when the browser window is minimized: polling runs inside
 *   a Web Worker to bypass background-tab timer throttling.
 * - Detects SPA navigation (`pushState` / `replaceState` / `popstate`), so the
 *   notification fires as soon as you land on `/settings/usage`, even from
 *   another route on claude.ai.
 * - Optional sound cue (880 Hz, ~400 ms, generated via the Web Audio API),
 *   toggled from the Violentmonkey / Tampermonkey extension menu - useful on
 *   Firefox where OS notifications are short-lived.
 * - Persistent settings via `GM_setValue` (no `localStorage` pollution).
 *
 * ## Permissions
 *
 * - `GM_notification` - desktop notifications
 * - `GM_registerMenuCommand` - sound toggle in the extension menu
 * - `GM_setValue` / `GM_getValue` - persistent settings
 *
 * ## Privacy
 *
 * The script reads the percentage and reset countdown directly from the DOM of
 * the official Claude usage page. No network request, no third-party service,
 * no telemetry.
 *
 * ## Compatibility
 *
 * Tested on Firefox + Violentmonkey and Chrome + Tampermonkey.
 *
 * - Chrome + Tampermonkey: fully persistent OS notifications (kept until
 *   clicked).
 * - Chrome + Violentmonkey: persistent thanks to the `onclick` parameter.
 * - Firefox + Violentmonkey: notifications fire but are short-lived (Firefox
 *   limitation, Bugzilla #1187270). Enable the sound option for a reliable
 *   signal when the window is minimized.
