+ * NOTE: this is *not* the frontend tool-registry IDs and several entries
+ * here have already drifted from the real registry endpoints (e.g. `merge`
+ * vs `merge-pdfs`, `compress` vs `compress-pdf`, `ocr` vs `ocr-pdf`).
+ * Tests still pass because the frontend's `useEndpointConfig` defaults
+ * absent keys to `enabled: true`, so a wrong key is functionally the same
+ * as a missing key — every endpoint reports enabled either way.
+ *
+ * TODO: derive this from `getAllApplicationEndpoints(registry, …)` instead
+ * of hand-maintaining it. That requires extracting endpoint metadata out of
+ * `useTranslatedToolRegistry` (currently a React hook with deep i18n + tool
+ * component imports — can't be called from Node-side Playwright setup) into
+ * a pure-data module both the hook and this helper can import.
