/**
 * D-4 — promote click IDs to person properties.
 *
 * Reads platform click-ID parameters (fbclid, ttclid, gclid, etc.)
 * from the entry URL and writes them as $initial_<param> via
 * setPersonPropertiesOnce. Survives the lifetime of the person record;
 * pairs with Conversions API back-channels (Meta CAPI, TikTok Events
 * API, etc.) when clients eventually run paid ads.
 *
 * See docs/plans/current/2026-05-04-sdk-default-instrumentation-spec.md (D-4).
