-Recompile Almagro with fontTools to regenerate valid cmap/table directories and WOFF2 container. Permit the configured LAN host as a Next development origin so chunks and HMR websocket are accepted.
+Admin client must treat HTTP 204 as success instead of attempting JSON parsing. Category UI confirms cascading impact, disables duplicate deletion, reloads tree and shows persistent success/error feedback.
