about

nx_iot_control_page.nx -- emit a ZERO-JS, CROSS-BROWSER IoT CONTROL page. Operator 2026-06-22: "work via nishi browser and 3rd party like chrome/firefox/edge and simple for other people to use aka reproducible." The cross-browser + reproducible answer is SERVER-RENDERED HTML + CSS with ZERO <script>: controls are real <form> POSTs to the hub's /home/cmd, so they actuate in EVERY browser with nothing to install (the same no-JS doctrine the reader arc proved). Capability-driven (nx_iot_capability): a switch gets On/Off, a colour bulb gets brightness/colour/warmth/scene -- chosen per device, never hardcoded. Library organ: cp_head/cp_card/cp_foot/cp_find + a demo main() (the gate calls the functions; on import the demo main is stripped). NEVER-BRICK #26: the page only emits on/off/brightness/scene COMMANDS (no firmware). license_tier: ORIGINAL
