Yuanqs-pine/DSH-Transparent-Frosted

(UI enhancement) Frosted-glass background for the whole app: one slider blends from a genuinely blurred, milky frost to a fully transparent page, and every region, control and expanded page moves as a single sheet painted on body::before; the settings page has its own independent slider, and an optional whale particle overlay reacts to the pointer. In a browser the plugin paints its own dark backdrop behind the frost. On the desktop the effect is painted on the app window itself: the dsh Windows window has never been transparent (only macOS gets a vibrancy window), so on Windows the page shows the window background instead of your wallpaper, while macOS keeps the native transparent window. Works on every dsh version (checked up to 0.2.2-alpha.3).
