A Node 24 process that claims render jobs from Studio's render lane (/v1/studio/render), renders one output, asks the lane where it goes, PUTs it there, and completes the job with the measured result. Five ops: render.html (exact PNG/JPEG/WebP or one-page PDF), render.document (PDF, DOCX, Markdown), render.slides (PPTX with notes, or a 1920x1080 PDF per slide), render.composition (@hanzo/frames), and video.edit (ffmpeg: trim, fit, join, libass captions, overlays, mixed audio). Every page runs in a fresh browser context behind request interception and a per-job egress proxy, which frames' Chrome and Node go through too; ffmpeg opens only local files through a demuxer whitelist. The image is node:24-bookworm-slim with Debian's chromium-headless-shell (amd64 and arm64), ffmpeg and fonts, built for both platforms by hanzoai/ci.
