- Reduce debug level to 1 (errors only) for production builds
- Replace BLE pause/resume with full deinit/reinit during HTTP uploads (~25KB freed)
- Add 60s boot report delay for fast post-deploy connectivity verification
- Add device_id to BLE batch and heartbeat request bodies
- Correct API host to http:// (plain HTTP, not HTTPS)
- Add HTTP response logging and CV entry/exit serial logging
- Create root README.md with operator setup and architecture overview
- Update design spec: HMAC format, BLE memory approach, request body shapes, reporting intervals

loopTask: cv_init() created a CVState{} temporary (9KB background
array) on the stack — fixed by initializing members directly.
cam task: cv_process() had uint8_t fg[CV_PIXELS] (9KB) as a local
variable — made static, matching the existing fg_copy fix.
cam task stack bumped from 4096 to 8192 for headroom.
Also: switch to 4MB OTA partition table (TimerCamera-F has 4MB flash,
not 8MB), add CONFIG_ARDUINO_LOOP_STACK_SIZE=16384 build flag,
upload_speed=115200 and --no-stub for reliable CH340 flashing.

Add camera.h/camera.cpp for TimerCamera-F OV3660 init and box-filter
downscale to 96x96 grayscale. Add espressif/esp32-camera to lib_deps.
