// ============================================================
// BODYCAM REVISION
// XIAO ESP32-S3 Sense / ESP32-CAM Sense
// Axon Body 3-style behaviour
//
// Velxio-optimised revision
//
// Optimisations:
// - Non-blocking buzzer
// - 400 kHz I2C
// - Reduced OLED redraws
// - Recording display updates once per second
// - No redundant display transfers
// - Faster startup/transition timing
// - 1 ms cooperative loop
// - Startup BMP preserved
// - Robust double-click detection
