- logbuf.py: bounded in-memory log ring buffer + a logging.Handler on the root logger; GET /logs serves it; the control page polls it into a console pane — so runs are monitorable without `docker logs`. worker now logs autoscale moves (one line per change, with jobs/s + util + VRAM) and job failures (job + image + reason); detectors already log load/disable. - Restyled the whole control page: a proper dark layout with a header + live connection pill, cards (Control / Status / Logs), a styled Auto switch + worker stepper, status tiles, separate GPU-util and VRAM meters, and the log console. No longer feels like an afterthought; all the existing control hooks are preserved.
