The bar was 611px inside a 600px viewport at the bottom of the Compact band, and 862px while a scan with a real library's title ran, because `job-indicator` is `hidden` when idle and 235px wide when it is not. `body` is `overflow-x: auto`, so a user got a horizontal scrollbar on a shell #24 promised would not need one — and the band is 600 to 899 with work in flight, not the 600 to 610 the idle measurement suggested. `services/top-bar-fit.ts` is `page-header`'s treatment one bar up: a ResizeObserver, every pass starting from all-visible, hiding the lowest-priority child until it fits. Measured rather than breakpointed because three of the five children are as wide as their content — the library filter by the longest library name, the indicator by the running job's title, the search box by its view-scoped placeholder — so any width picked is right for one library, one job and one view. What yields is decided by #24's own sentence, which rules out the two cheapest candidates in the Direction. Hiding the library filter takes away an action, since it is the only control in the app that selects a library (filed as #148, which is the phone already doing it), and collapsing search to an icon is #57's, which is blocked behind #62. So the wordmark yields first — a brand the window title bar repeats, and visually-hidden rather than `display: none` because that h1 is the document's heading — and then the indicator's label, leaving the ring, which the component already does below 600px and whose live region announces the state either way. "Fits" is the children against the content box, not `scrollWidth` against `clientWidth`: `scrollWidth` counts the left padding and not the right, so the first version read 700/700 with the indicator sitting in the whole right gutter. And the bar does not resize when a job starts, which is the case this is for, so every child is observed too. Pinned before it was fixed, as the issue asks. On the unfixed build the new spec fails at 600 idle and at 600, 800 and 900 with a job, and passes at 390, 899 and 1440; `layout-overflow.spec.ts` gains 600x600 and failed there. That spec asserts on the *shell*, so it was green throughout this defect — the per-child measurement is #69's lesson, and it is what caught the gutter case above. Closes #143

Play your music
- Plays MP3, FLAC, OGG Vorbis, and WAV
- Play, pause, seek, and volume control with a mute toggle
- Gapless, glitch-free seeking backed by a read-ahead buffer
- A queue you can add to, reorder, and shuffle, with play-next support
- Shuffle and repeat (off / all / one)
- Picks up right where you left off — remembers your track, position, and volume between sessions
- Media-key and MPRIS support on Linux, so your desktop's playback controls just work
Keep your library organized
- Point it at your music folders and it scans them automatically
- Reads tags and embedded cover art, and de-duplicates artwork so it isn't stored twice
- Incremental sync — only new or changed files get reprocessed, and deleted files are cleaned up
- Browse by album, artist, or genre, or search across everything
- Mark favorites and see what you've been listening to with play history
- Edit track tags directly when something's off
Playlists
- Create playlists, drag tracks in, and reorder them
- Smart playlists that build themselves from rules (by genre, rating, play count, and more)
- Pin a default playlist and spot duplicate tracks at a glance
Discover and clean up (powered by MusicBrainz)
- Explore — browse artists, releases, and genres from the MusicBrainz catalog, not just what's already in your library
- Auto-tag — match your files against MusicBrainz to fill in correct artist, album, and track metadata, with a review step before anything is written
- Lyrics search — find a track by a line you remember

Building from source
YellowJacket is built with Go and a Lit/TypeScript frontend, bridged by the Wails framework.
Prerequisites
| Tool | Version |
|---|---|
| Go | 1.25+ |
| Node.js | 22+ |
| pnpm | 10+ |
| Wails CLI | v3 — vendored, no install needed (go tool wails3) |
The Wails v3 CLI resolves from the tool block in go.mod, so there is nothing
to install globally; make setup fetches it with the rest of the tooling.
On Linux, install the system libraries Wails needs. v3 builds against GTK4 + WebKitGTK 6.0 by default:
sudo apt-get install libasound2-dev libgtk-4-dev libwebkitgtk-6.0-dev # Debian/Ubuntu
sudo pacman -S alsa-lib gtk4 webkitgtk-6.0 # Arch
A machine without webkitgtk-6.0 can still build with -tags gtk3 against the
older WebKit2GTK 4.1 stack, but that is an escape hatch, not what CI or a
release builds.
macOS and Windows need no extra system packages. Run go tool wails3 doctor to
check your environment.
Build
make setup # install tooling and git hooks
make dev # run with hot-reload
make build-prod # produce a release binary
