/**
 * order3000 ad-click attribution — first-party capture of the click identifiers
 * that appear on an ad's landing URL (Google Ads auto-tagging `gclid`/`gbraid`/
 * `wbraid`; Meta `fbclid`). A reservation made later in the session is then
 * attributed to the originating ad click and reported to the ad platform
 * server-side — Google Ads offline conversions and the Meta Conversions API.
 *
 * **Provided by order3000 so every consumer captures attribution identically,
 * without re-implementing this logic.** Wire it in two lines on the restaurant
 * frontend:
 *
 *   - call `persistAdClickIdsFromUrl()` once on landing (every page), and
 *   - spread `getAdClickIds()` into the `reservations.make(...)` payload on
 *     submit.
 *
 * No Google/Meta script is ever loaded — these are plain query params we read
 * ourselves and store in first-party cookies (browser-only; every function is a
 * no-op when `window` is undefined, so it is safe to import in SSR code).
