 What's new in Periscope.
 
+## 2.52.0 — 2026-09-20 — Native leftover frontend overlay
+
+Dashboard, project, report, progress, admin, feedback, marketing, and the HTTP client (`lib/api.ts`, `types.ts`) are original Periscope UI in `periscope/src/frontend`. Docker still copies OSS then src. Routes, API contracts, and layout are unchanged. Billing/Clerk/analytics stay imported seams. Auth/JWT untouched. Pad≠Via unchanged.
+
+- [New] Frontend types + API client rewrite (export names preserved).
+- [New] App and marketing pages rewrite so overlay wins without a product restyle.

 ## 2.51.0 — 2026-09-20 — Native Settings, FastAPI app, leftover routers
 
 `config.py`, `main.py`, `pipeline_worker.py`, and leftover HTTP routers (`admin`, `contact`, `deps`, `feedback`, `pipeline`, `projects`, `reports`, `survey`) are original Periscope code in `periscope/src`. Inherited copies stay on disk. `routers/auth.py` is unchanged. JWT middleware remains leftover. Frontend product chrome is still the Docker overlay (src pages already win for library/PCB/placement/sign-in). Pad≠Via unchanged.
