Measured at the reference device's 424x439, every button here was 33x21px -- in the bottom bar and on the full-screen view alike. #56 reports them as "the most important thing in the mobile app and they are tiny", and that is the number behind it. The context is a **property, not a media query**, and that is the whole design. Everywhere else in this app a component states what it drops at phone width itself, because a media query inside a shadow root is answered by the viewport and that is the honest signal. Here the two hosts want different answers at the *same* viewport: on a phone the bar wants three controls sized for a thumb and now-playing-view wants five, larger still. So the host says which context and the viewport says which size band, and neither alone can express it. Play/pause alone goes above the 44px floor. A row of five identical squares says every action is equally likely, which is not true of play -- "large play/pause, adequate prev/next" is the Direction, and a spec caught that the first version had sized all three the same. Two things that fail silently: The desktop bar must not move, and a `<button>` does not inherit its font from its parent -- the UA stylesheet gives it one. So a generic `font-size: inherit` is not the no-op it reads as: it took every desktop control from 33x21 to 36x24. The box rules take a zero fallback and the font-size rules are scoped to the two contexts that set one. And the art on now-playing-view overflowed its own box, drawing over the header above and the title below, because `aspect-ratio: 1` with a definite width derives a height that nothing bounds -- 60vh bounds the viewport, not the room left over. `max-height: 100%`. Pre-existing; found by reading a screenshot, which is the only tier that can see it. What is left is #172: with the transport at 172px of a 439px screen the art is a 39px sliver. Closes #56

- Edit track tags directly when something's off
Playlists
- Create playlists, drag tracks in, and reorder them

- 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

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
