+## adventurelog: photos render — the backend's own paths go to the backend (2026-09-13, R-483)
+
+The operator measured it in a browser: on his k3s install a photo uploads and renders; on demo-hp it
+uploads and renders as a broken "Uploaded content". The diff against `homelab-manifests`'s
+`adventurelog-system/adventurelog.yaml`: its ingress sends `/media`, `/static`, `/admin` and
+`/accounts` to the backend and only `/` to the frontend; the catalog template sent every path to the
+frontend, which does not serve `/media`, so every photo URL was a 404. Now the backend service carries
+its own traefik router for those four prefixes (priority 20; the frontend router is priority 10). The
+frontend's `/api` and `/auth` proxy stays as it is — that is also the k3s shape. Nothing else differed
+(`PUBLIC_URL`, `CSRF_TRUSTED_ORIGINS`, `ORIGIN`, `BODY_SIZE_LIMIT` all match). No version moved.
