This PR contains various improvements and cleanups to the configuration and JavaScript code. Key changes include:
- Adding simple comments to `jsconfig.json`.
- Improving config: `bud.wpjson.set` replaces `bud.wpjson.settings`. Note that `bud.wpjson.settings` is not deprecated.
- `bud.wpjson.settings` now disables `dropCap` by default.
- `app.js` and `editor.js` now use `if (import.meta.webpackHot)` instead of optional chaining, since `import.meta.webpackHot` is not a real method and using optional chaining might cause errors.
JavaScript detection with a class name on the body or html element tends
to go unused even by websites that have it set up. Instead, we recommend
that developers write progressively enhanced components that are styled
for non-JS usage by default. Increase specificity, use the cascade, or
code split to apply progressively enhanced styles.
