## Changes Introduces two new files in `packages/common`: - **`telemetry-first-touch-store.ts`** — a module-scoped singleton that holds first-touch attribution data (referrer, UTM params, page URL) in memory. Writes once on first load, cleared after the initial pageview event fires or on opt-out. No device storage involved. - **`useFirstTouchStore.tsx`** — a React hook that captures attribution data on initial page load and writes it into the store, gated on the `enabled` flag so it only runs where consent has been handled. Trade-off: data is lost on a hard reload before consent is granted — accepted edge case per GROWTH-656. Follows the same module-scope pattern already used by `posthogClient` and `consentState`. ## Testing - Verify first-touch data is captured on initial load and readable by `PageTelemetry` after consent - Verify no cookie is set before consent - Verify data is cleared after initial pageview fires GROWTH-656
