Hotkey brightness control for Windows monitors via DDC/CI, plus a dimming overlay for when 0% is still too bright.

A hotkey-driven monitor brightness tool for Windows. From 100% down to 1% it sets the hardware backlight over DDC/CI (VCP code 0x10), so the panel actually gets darker. Once brightness reaches 0% and the screen is still too bright, a black fullscreen overlay with variable opacity keeps dimming past the hardware minimum. Multi-monitor aware: a hotkey affects the monitor the mouse pointer is currently on. Monitors are identified by EDID rather than by OS handle, so the configuration survives replugging and port changes. An OSD shows the current value, and a system tray icon offers live per-monitor status plus warnings while degraded. Performs no network I/O of any kind: no telemetry, no update checks, no crash reporting. Note: the overlay does not cover exclusive-fullscreen games or certain Windows system UI such as the taskbar and Start menu. Laptop internal panels do not speak DDC/CI and are not supported. The binary is not code-signed, so Windows SmartScreen warns on first run.
