Added

• Subtitle Burn-In Style Controls: Added subtitle styling options in the Subtitles tab for burned-in subtitles, including font family (system font list), font size, text color, outline color, and vertical position presets.
• Subtitle Style UI Primitives: Added reusable Select and ColorPicker UI components (plus chevrons up/down icon) to support compact dropdown and color selection workflows in settings panels. Changed
• Subtitle Filter Mapping (FFmpeg): Extended conversion config and ffmpeg subtitle filter building to map subtitle style selections into force_style (font name/size, primary color, outline color, and alignment), including safe hex-to-ASS color conversion and coverage tests.
• Surface/Control Visual Consistency: Unified card/input/button highlight styling and related control spacing across preview, file list, logs, update dialog, and workspace shells for more consistent panel rendering.
• Subtitle Styling Localization: Added new subtitle style locale keys across all supported UI dictionaries for the new styling controls and hints. Fixed
• Trim Timeline Edge Alignment: Fixed preview timeline marker alignment so the current-time playhead and trim handles share the same center point and stay visually aligned at boundary values (0%/100%).
