100% Responsive Delete Key: Re-engineered the keyboard engine using direct matrix bitmasking (status.del). This bypasses the character buffer lag, ensuring the top-right backspace key works instantly, every time.

Epoch-Precision Timer: Unlike standard timers that can drift during system tasks, our countdown logic uses Unix Epoch calculations. It calculates the exact second in the future for the alert, making it bulletproof even during WiFi syncs.

Hardened WiFi Logic: Built-in recovery for the "Connecting" screen. If a connection fails or a password is wrong, the app gracefully times out and returns you to the menu instead of freezing.

Burn-in Protection: Dynamic pixel-shifting screensaver logic is active during clock mode to protect the long-term health of your Cardputer's display.
