/**
 * Plausible Analytics adapter.
 *
 * @see https://plausible.io/docs/excluding-localstorage
 *
 * Documented opt-out mechanism (from Plausible docs):
 * - Key: `localStorage.plausible_ignore`
 * - Value: `'true'` to exclude, remove to include
 * - Console message when active: "Ignoring Event: localStorage flag"
 *
 * Plausible is privacy-focused and doesn't use cookies, so consent is
 * technically not required. However, some site owners want to respect
 * a user's explicit opt-out preference.
 *
 * Plausible checks `localStorage.plausible_ignore` — if set to "true",
 * it skips all tracking and logs "Ignoring Event: localStorage flag"
 * to the console.
 *
 * ```js
 * registry.register(createPlausibleAdapter());
 * ```
