cantonddy/zone — reverse-engineered prompt

Build me a dark modern web app called Zone New Checker for checking IPTV account details. It should support Xtream Codes with server URL, username, password, and Stalker or MAG portals with portal URL and MAC address.

In single mode, I want to enter one account, press Check, see if it works, and show safe info like expiry, max connections when available, real URL, port, timezone, portal IP for Stalker, and channel count when possible. After a successful check, show a playlist browser with categories or genres, channels, search, sorting, logos through a safe image proxy, and a mobile friendly layout.

Also add bulk mode where I can paste many lines, validate them with safe limits, stop the run, see counters, and copy results. Don’t add streaming, playback, M3U export, databases, or server side credential storage. Keep credentials only in the browser when remembering inputs. Make it ready to run locally and deploy to Vercel, and look up current docs online if needed.
