 ## Features
 
 - **6-DoF gyro + accelerometer** via LSM6DS3 with complementary filter
-- **Hardware tap detection** — single tap = left click, double tap = right click
-- **BLE HID mouse** — works natively on Windows, macOS, Linux, Android, iOS
-- **BLE Battery Service** — charge level visible in OS Bluetooth settings
-- **Web config UI** (`web/index.html`) — configure over BLE from any Chrome/Edge browser, no app install
-- **Flash persistence** — config survives power cycles (LittleFS)
-- **Live IMU stream** — 20 Hz gyro/accel data streamed to the web UI visualiser
-- **Live telemetry** — temperature, uptime, click counts, gyro bias RMS, recal count
-- **Temperature compensation** — gyro drift correction by Δ temperature since last calibration
-- **Auto-recalibration** — recalibrates automatically after 5 minutes of idle
-- **Configurable charge rate** — OFF / 50 mA slow / 100 mA fast via BQ25100 HICHG pin
-- **Boot-loop detection** — 3 rapid reboots trigger safe mode (config service disabled, flash wiped)

 | LED | Pattern | Meaning |
