Module screen_lock 

Screen Lock

Provides a fullscreen lock screen with password authentication. Triggered via Ctrl+Alt+L or idle timeout. Renders a dark gradient background with a padlock icon, username, and dot-masked password field. Integrates with the security/auth module for credential verification.

All rendering uses integer math only (no floating point). Text is drawn via crate::graphics::font8x16::glyph() into a u32 pixel buffer (0xAARRGGBB native-endian).
