`.expand` is the phone's only route into the full-screen now-playing view. It is absolutely positioned with `z-index: auto` over `.cover-art`, which is a *later* sibling with the same z-index, so the two tie on paint order and the later one wins. An `<img>` costs nothing there; a track with no artwork renders a placeholder `wa-icon`, which takes every click aimed at the button underneath it. So the control did not work whenever the current song had no cover, on the one platform that has no other way in. Nothing to do with the fixture: any library has untagged files. Measured at 390px with elementFromPoint at the button's centre — the icon with a placeholder, the button with an image, and the button either way with the z-index. Chosen over `pointer-events: none` on the art, which would take the cover preview's mouseenter with it, and over reordering the DOM, which leaves the same tie to be won by the same accident in the other direction. This was filed as an e2e flake, and the diagnosis was wrong: it failed on both engines three times across two branches that could not have caused it, and passed on re-run each time, because the spec starts the *first* row of the track list and which track that is depends on the order the scan inserted rows — the same root cause as #156. The new spec picks a track *for* having no artwork, and asserts the placeholder is rendered rather than assuming it, so it cannot quietly go back to measuring the easy case. Two things it has to get right, both already documented traps: the track must be the 90-second one, since a 2-second one finishes before the assertions run; and `library.Track.CoverArt` is empty for all 31 fixture rows, so "the first track with no cover art" selects nothing in particular and picked a short one. Verified by mutation: without the z-index the new spec fails on the click in 30s, and the pre-existing one beside it passes, which is exactly how this survived. Closes #150
YellowJacket Frontend
This directory contains the frontend for YellowJacket.
Dependencies
There are a couple of tools that are required to build and use the frontend.
vitefor- transpiling typescript
- bundling the final "package" that is useb by the webview
- running a dev server with hot-reloading
- configured with the
vite.config.tsfile in this directory
pnpmfor managing frontend dependency packages
There are a handful of dependency packages that we use directly in the frontend.
picocssfor basic CSS while developinglitfor a simple but powerful wrapper around Web Components
Lastly, there are some dependencies that only benefit development
tsservercomes bundled with vscode and can be used as an LSP with other editors usingtypescript-language-server- Used for autocomplete, syntax highlighting, etc.
- This can be configured with the
tsconfig.jsonfile in the root of the project- NOTE: your configuration should align with the
viteconfig so you get in-editor feedback that aligns with how the build will be done.

Development
Ideally, you would use the frontend in the wails app as the frontend depends on the Go bindings generated by Wails.
You can do this by running wails dev in the root of the YellowJacket repo.
If you want to run the frontend standalone, make sure the Wails go bindings have been generated with wails generate modules.
Then, you can run pnpm dev to run the vite dev server.
For more information on what commands are available, refer to package.json.
Code
Web Components
Our frontend is based off of Web Components, a standard that provides native browser encapsulation of components that can include HTML, CSS and Javascript all together.
Instead of writing these components manually in Javascript, we utilize lit as a wrapper library.
Typescript
To better integrate with our tooling and to provide a better developer experience with strong typing, we have written all functional frontend code in Typescript. Vite serves as our Typescript transpiler.
Important Files and Directories
NOTE: most of these directories have aliases defined in tsconfig.json and vite.config.ts so that we may refer to them by shorthand when importing.
