-Routes: `GET /upload` (HTML upload form), `POST /upload` (multipart), `GET /manage` (list of photos), `GET`/`POST /manage/edit/{slug}` (edit caption and date), `GET`/`POST /manage/delete/{slug}` (confirm, then delete), `GET /health`.
+Routes: `GET /upload` (HTML upload form), `POST /upload` (multipart), `GET /health`, and with `-manage`: `GET /manage` (list of photos), `GET`/`POST /manage/edit/{slug}` (edit caption and date), `GET`/`POST /manage/delete/{slug}` (confirm, then delete).
 
 In production nginx sits in front: serves `public/` directly, proxies `/upload` and `/manage` to localhost, htpasswd on both. Note `/health` is **not** proxied — nginx only forwards `location /upload` and `location /manage`, so anything outside the box can only reach those two.
 
 ### Managing photos
 
-`manage.go` holds the `/manage` handlers, kept apart from the upload code in `server.go`. The pages are rendered on request from the sidecars (not generated into `public/`), and nothing on the public site links to them. Constraints worth knowing before touching it:
+`manage.go` holds the `/manage` handlers, kept apart from the upload code in `server.go`. They are only registered when the binary runs with `-manage` (NixOS `services.photogallery.manage.enable`, which also adds the nginx location); without it the paths 404 and there is no edit or delete code path at all. The pages are rendered on request from the sidecars (not generated into `public/`), and nothing on the public site links to them. Constraints worth knowing before touching it:
 
 - An edit only rewrites the `.toml` sidecar. Any key other than `caption` and `date` in a hand-written sidecar is dropped, same as on upload.
 - Slugs from the URL are matched against the photos actually in `content/`, never joined into a path.
