Per feedback — one modal with a view transition beats close+open. Clicking
'Download' now swaps the get-modal's detail body for the download view (quality
target + owned verdict + per-source search) with a '← Back to details' button;
the selection-only sections (episodes/next/follow) and the Full page/Download/Add
buttons collapse, the all-related movie bits stay.
- video-download-modal.js → video-download-view.js: now a reusable RENDERER,
VideoDownload.render(container, opts), not its own overlay. A future YouTube
trigger can render the same view into its own container (still universal).
- get-modal: enterDownload/exitDownload toggle the in-place view; stashes the
owned file on modalState to feed the verdict. Removed the separate .vdl
overlay/hero/close CSS; added .vgm-dl/.vgm-back + [hidden] guards; chips now
pick up the modal's --vgm-h vibe hue.
Pure front-end; balance + div + css brace checks clean.
