A paper-trading platform that pairs the entire NSE universe and AMFI mutual-fund catalogue with an AI coach designed never to give buy or sell advice. A Time Travel mode replays real Indian market crises — demonetisation, COVID, Adani-Hindenburg — day by day, so a virtual portfolio's held vs panic-sold lines diverge over actual historical closes.

ESP32 firmware drives the dual-door magnetic-lock relays; an ESP32-CAM streams MJPEG over the same closed subnet; a Flutter app stitches them together over plain HTTP on 192.168.4.x. Fail-secure boot order, 800ms relay-fire cooldown, hand-rolled JPEG SOI/EOI byte-stream decoder, and an optional Hinglish voice assistant with five-layer persistent memory. The homeowner owns the firmware.
