nx_monitor_html.nx

nx_monitor_html.nx -- sovereign substrate-emitted browser monitor. Emits a single static HTML+vanilla-JS page that runs in the operator's existing browser (Firefox/Chrome) and connects DIRECTLY to the Qidi's Moonraker WebSocket + camera service. No nginx, no Mainsail, no Fluidd, no Vue/React/Tailwind, no npm dependency -- every byte the browser receives is substrate-emitted text. Per NISHI_3D_PRINT_BULLETPROOF_PREFLIGHT_ROADMAP §2: the operator's browser IS the rendering layer until nx_browser ships native; the SUBSTRATE-side (this primitive, telemetry parsing logic, etc.) is 100% sovereign Nishi. What the emitted page does: 1. WebSocket: ws://<host>:<port>/websocket -> Moonraker subscribe to print_stats + extruder + heater_bed + gcode_move + virtual_sdcard 2. MJPEG: <img src="http://<host>:<cam_port>/?action=stream"> 3. 6 telemetry tiles: state, progress, hotend, bed, Z, ETA 4. 4 buttons: pause / resume / cancel (confirm) / EMERGENCY STOP (M112 via /printer/emergency_stop) 5. Half-print detection: JS polls every 5s, alerts if Z hasn't advanced in 2 min while printing Composes nx_moonraker_client's buffer write helpers (no duplication per [[feedback-symbol-collision-prevention-pre-write-check]]). Reuses existing operator-facing browser (third-party until nx_browser ships) for RENDERING; refuses every other third-party dependency per "no 3rd party bullshit" directive. license_tier: ORIGINAL
