+ * The compliance controls on the privacy policy and terms.
+ *
+ * These used to live in `apps/web/src/locales/__tests__/legalParity.test.ts` and
+ * assert that two hand-maintained copies said the same thing. Google Play requires
+ * the policy inside the app and the policy at the store-listing URL to agree, and
+ * the two copies HAD drifted: mobile's Terms were missing the uploads warranty, the
+ * DMCA route and the liability cap for months.
+ *
+ * There is one copy now — this file — read by the mobile app directly and by the
+ * website through `apps/web/src/locales/catalog.ts`. Parity is structural rather
+ * than asserted, which is why the assertions moved here rather than being deleted:
+ * the *content* rules were never about parity. Web additionally forbids itself from
+ * shadowing these namespaces (`apps/web/src/locales/__tests__/legalShadow.test.ts`),
+ * so "two files must match" became "there is one file, and web may not override it"
+ * — strictly stronger.
+ *
+ * A failure here is not a typo. It is either a compliance gap or a promise made to
+ * one set of users and not the other.
