Glass texture theme

Key features

• The header, sidebar, composer, stats line, and trajectory view all become panes of frosted glass.
• Two modes are built inFloating Glass restyles the layout into floating cards, while Compatibility Mode keeps the stock layout untouched and only swaps the material to glass — so other plugins' UI gets the same treatment automatically.
• Glass blur, frost amount, and the backdrop are all adjustable from the settings card — pick a living fluid or drop in your own wallpaper (with its own blur and frost).
• Switch it off and the stock UI comes back exactly, with no source changes to DSH itself.
