The phone drew a grey box over the bounding rect of whatever was tapped, which is the web view saying what it is. It is gone in one declaration: `-webkit-tap-highlight-color` is inherited and an inherited property crosses a shadow boundary, so `html` in index.css reaches every shadow root in the app. Measured three roots deep, rgba(0, 0, 0, 0.18) before and rgba(0, 0, 0, 0) after. Removing it removes the only touch feedback several surfaces had, so the press state is part of the same change rather than a later polish item — with the highlight gone a held row measured the *hover* tint, which on a phone is synthesised by the hold itself and outlives it. The four lists' rows, the tab bar, the sidebar's destinations and the shared context-menu item take --yj-press-overlay on :active; the cards already had scale(0.97). The press selector carries a state class because a row is .track-row.selected.active, so a bare :active shows nothing on the row a phone is most likely to press. And those surfaces' hover tints move behind (hover: hover) and (pointer: fine), which is #68's gate applied to a tint rather than a revealed control. user-select, the other half of the Findings, was already done: the first rule in index.css covers the shadow roots for the same reason. touch-action: manipulation is declined — the 300ms delay it is offered for is already absent on a width=device-width viewport, and what it would really change is the gesture stack tuned by measurement on a device this session cannot measure. Closes #54
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.
