HUD Appearance Customization:

• Added new fields (opacity, border_radius, font_size) to the HudConfig struct, with appropriate defaults and serialization/deserialization in the config loader and saver (src/config/hud.rs). [1] [2] [3] [4]
• Updated the HUD CSS generation to use these new config values, replacing the previous dependency on StyleConfig (src/ui/hud.rs). [1] [2] [3] [4] [5] [6]

Settings UI Enhancements:

• Added a new "HUD Appearance" section to the HUD settings page, allowing users to adjust opacity, border radius, and font size interactively. Changes are saved to the config and reflected live (src/ui/settings/hud.rs).

Code Cleanup:

• Removed the unused import of StyleConfig from src/ui/hud.rs as it is no longer needed.
