Adds mobile-first responsive CSS for the custom settings menu and chapters overlay, including adaptive sizing, touch-friendly interactions, and prevention of body scroll when overlays are open. Updates CustomSettingsMenu.js to detect mobile devices, handle touch events for menu items, and manage scroll locking and haptic feedback for a better mobile user experience.
Adds direct access to the subtitles submenu from the subtitles button, updates the button's active state based on subtitle selection, and dispatches a custom event on subtitle state changes. Also cleans up unused static video.js files and enables the SubtitlesButton CSS.
Moved tooltip logic for custom video player controls (autoplay, next video, settings) into VideoJSPlayer.jsx, removing direct 'title' attributes from button components. Improved dynamic tooltip updates for the autoplay toggle. Removed unused static video_js CSS and JS assets.
- Settings menu content - split into separate variables for maintainability
