#### X11 keyboard and mouse input shield with corner HUD and auto-unlock timer

A lightweight Linux X11 keyboard and mouse input shield inspired by KeyFreeze.
Disclaimer: This project is an independent open-source tool and is not
affiliated with, sponsored by, or endorsed by KeyFreeze. Input grabbing uses
X11 XGrabKeyboard and XGrabPointer; Wayland-native windows isolate input
sessions from X11 grabs.

FEATURES

* Keyboard and Mouse Input Shield: block accidental keyboard presses, mouse
  clicks, or both with a configurable 3s or 5s grace countdown timer.
* Translucent Corner Status HUD: floating always-on-top corner indicator
  displaying the unlock chord (Ctrl+Alt+U), live remaining safety countdown,
  and real-time blocked input counters.
* Mandatory Safety Auto-Unlock and Tray Controls: guaranteed automatic grab
  release timer, instant unlock chord interception, system tray controls,
  live X11 diagnostics, session history, CSV export, and EN / VI UI.
