Build flow

Install ESP-IDF matching Espressif P4 toolchain requirements, activate environment, then:

cd p4_gemini_chat
idf.py set-target esp32p4   # confirm precise target alias with Espressif release notes
idf.py fullclean build flash monitor

Export GEMINI_API_KEY (or whichever env var main sources expect) securely—never bake keys into firmware images.
