Media-scape theme for the DSH web UI: standing/character-art and video wallpapers (mp4/webm, local + online) with boot animation, base color schemes (single-source JSON + presets + picker), capsule host-element styling, ambient particles, background music player (covers/playlists/random), typing sound effects, and a draggable dock toolbar with a unified upload entry — wallpapers and music uploaded together (suffix-classified), mid-upload no-disk buffering, pause→.part snapshots with offset resume, filename+size dedup with "skipped" notices, and true-delete removal with list refreshes.
