+// Phase 4c pre-assemble helper — wait for detached BGM, then write status.
+//
+// audio.mjs may launch Lyria / MusicGen in a detached process so voice work can
+// keep moving. Before assemble-index.mjs decides whether to emit the BGM audio
+// track, this script gives the background renderer a bounded chance to finish
+// and converts log/process state into a small bgm_status.json file.
+//
+// Always exits 0 for normal pipeline use: missing/failed BGM should not block a
+// voice/captions/SFX render. Structural invocation errors still exit 1.
+//
+// Usage:
+//   node wait-bgm.mjs --audio-meta ./audio_meta.json --hyperframes . \
+//     [--timeout-ms 120000] [--interval-ms 2000] [--out ./bgm_status.json]
