1// nx_roku_catalog_emit.nx -- SOVEREIGN Roku media-catalog FEED emitter (R1b). Emits catalog.json -- the media
2// data backbone the Roku channel fetches at runtime (the Jellyfin/Plex model: thin client, server holds the
3// catalog). Each item = {id,title,kind,poster}. This is the generated-media NAMESPACE feed (kept separate from
4// any personal archive by construction). The feed is published to the server (nx_aw_push) as a GATED, outward-
5// facing step -- NOT done here. Emitted by an organ, never hand-written. license_tier: ORIGINAL
6//   nx_roku_catalog_emit [out.json]   (default /mnt/c/Users/elder/nishi_roku_catalog.json)
