Features

• 28 built-in themes in 7 categories (Dark, Light, Neon, Pastel, Nature, Retro, Special). Transitions are animated with color morphing between themes.
• You can now save your own themes, delete them, and import/export as .bttheme files.
• Volume profiles — capture your current per-app volume setup and restore it later. Exports as .btprofile.
• Added a volume slider in the media popup. Uses a custom track with translucent fill + gradient that picks up the album art dominant color.
• Cover art in the expanded view now applies a light gaussian blur (radius 2) when the source image is low-res (< 300px, typical for YouTube/Chrome SMTC thumbnails at 150x83). High-res sources like Spotify render sharp.

Technical

• RenderOptions.BitmapScalingMode=HighQuality on both AlbumArtBackground and ExpandedCoverImage — uses Fant resampling instead of default Linear
• SMTC async wait timeouts bumped from 500ms to 2000ms (TryGetMediaPropertiesAsync, OpenReadAsync, ReadAsync) — Chrome is slow to deliver thumbnails
• Extracted named color brush resources + ActionButtonBorder style in SettingsWindow.xaml to DRY up ~20 identical button borders
• Legacy media polling is now adaptive: 5s interval when idle, 500ms when media is active. Cuts CPU usage when nothing is playing.
• Removed dead EarTrumpetCustomizationSettingsPageViewModel (928 lines). Extracted ColorTheme model to its own file.
• Fixed VolumeSlider rendering on DeviceView, fixed album art timer not disposing on window close
• ColorPickerPopup fix: was using stale color reference
• VolumeIconGenerator: cleaned up redundant path generation
