Two unrelated things landing together.
Sticky scroll fix:
- The natural-top binding on both jump-nav and the sidebar reads
from `body-row.absolute-position.y` (a live, scroll-aware
lookup). The y formula was `max(natural-top + viewport-y, ...)`
— adding viewport-y on top of an already scroll-aware value
double-counted the scroll. During mid-scroll the bar drifted
ahead of the body row, opening a visible gap and briefly
overlapping the header.
- Drops `+ viewport-y` from both formulas. natural-top alone IS
the viewport-relative y the elements want to occupy; the
max() clamp just keeps them from going above the top.
- Initial position and sticky position are unchanged; only the
transition is fixed.
Artwork right-click menu (artist portrait + album cover):
- Both headers get a TouchArea on the artwork that opens a
PopupWindow + ContextMenu on right-click, positioned at the
cursor. Mirrors Tauri's `oncontextmenu` flow on the artist
portrait and album cover.
- Menu items match Tauri 1:1: Add image / cover, Change + Remove
(when a custom image is registered), divider, Open in
browser, Save as.
- New `crate::custom_artwork` JSON-backed store at
`<data-dir>/qbz/custom_artwork.json` keyed by artist name +
album id (mirror of the Tauri library's
`v2_library_set/remove_custom_*` persistence).
- ArtistState / AlbumState expose `artwork-url` (network URL for
Open / Save) + `has-custom-image` / `has-custom-cover` (drives
the Add vs Change/Remove menu rendering), both populated from
Rust at apply_artist / apply_album time.
- ArtworkActions global + main.rs handlers:
* open-in-browser → `open::that(url)`.
* save-as → `rfd::AsyncFileDialog::save_file()` + reqwest
download + tokio::fs::write.
* add-custom → `rfd::AsyncFileDialog::pick_file()` then
`custom_artwork::set_*` + flip the has-custom flag.
* remove-custom → `custom_artwork::remove_*` + reset flag.
- rfd added with xdg-portal + tokio features. external-link and
image-plus SVGs ported from Lucide.
Custom-image RENDERING (using the picked file in place of the
network artwork) is deferred — the store persists the choice and
the menu reflects it, but the displayed image still comes from
Qobuz. Next pass.
