 `consent.ts` holds the answer in module state and notifies `src/index.ts`, which
 relays `surface:consent` to every Surface iframe (and re-sends it on each
 `SEND_DATA` handshake, for forms that mount after the banner was answered).
-Omitted categories count as not granted. The categories mirror the form-render
-gate in `surface_forms` (`lib/client/thirdParty/`) — keep the message shape in

+Every call is a complete snapshot: omitted categories count as not granted. The
+categories mirror the form-render gate in `surface_forms`
+(`lib/client/thirdParty/`) — keep the message shape in sync with its
+`hostConsent.ts`.
+
+Each answer is also written to `window.__SURFACE_CONSENT__` and dispatched as a
+`surface:consent` DOM event, which is how a Forms SDK form on the same page hears
+it; the tag reads a snapshot the SDK left there if the SDK loaded first.
+
+`cookieTracking` also gates the tag's own host-side work, but only when the
+`<script>` carries `data-consent-mode` (read in `runtime-config.ts`). Until that
+page grants it, `SurfaceStore` skips identify, the `surfaceLeadData` cache, the
+journey cookies and forwards an empty cookie snapshot; `applyConsent()` starts
+them on a grant and clears them on withdrawal. Without the attribute nothing
+changes for existing installs.

+## Cookie consent
+
+Pages that run a consent banner load the tag with `data-consent-mode` and report
+the visitor's answer, in full, on every load and every change:
+
+```html
+<script
+  src="https://cdn.jsdelivr.net/.../surface_tag.min.js"
+  site-id="your-environment-id"
+  data-consent-mode>
+</script>
+<script>
+  window.SurfaceSetConsent({ adTracking: true, surfaceAnalytics: true, cookieTracking: true });
+</script>
+```
+
+With the attribute, the tag does no visitor recognition, sets no journey cookies
+and forwards no page cookies to Surface forms until `cookieTracking` is granted.
+Form rendering and submission work regardless. Without the attribute the tag
+behaves exactly as before. See `CLAUDE.md` for the message contract.
