Split slow cached monitor endpoint from the live stats. monitor_fast.php reads /proc/stat, /proc/meminfo, ZFS arcstats, and /proc/net/dev directly — no cache wrapper, 87ms response. Docker/vm/swap pulled from last full cache so mem card stays complete. Full monitor poll stays at 2s for everything else (GPU, containers, storage, etc).
