XIAO ESP32S3 camera web apps — AP (hotspot) mode

The board becomes its own WiFi hotspot. Clients join the board's SSID and the page is ALWAYS at http://192.168.4.1. No router, no internet needed. Best for classrooms: one board per student/team, isolated networks.

Read the xiao-esp32s3 skill (same repo) first for base workflow and pitfalls (especially: PSRAM flag mandatory, DTR reset-stuck recovery, no serial reads while a demo must keep running).
