Deployment (t4g2): media-worker gains font-dejavu (drawtext lower-thirds) and a dedicated produce-worker compose service running src/produce.ts — claims video_processing_jobs compose|mix by lane, renders assembled/ overlaid/voiced cuts, registers derived library assets. Deliberately its own process so a remote-lane box needs only Postgres + S3 + ffmpeg. Web: compose media attachments UI (t2), Producer panel in the video drawer (t5), collective creation + branding settings + shell branding (brandweb), mobile CSS (mcss: touch targets, icon sizing, safe areas).
