// Watch mode for both build environments (see vite.config.ts) so dist/ stays
// loadable while editing: clear dist/ once, then start a rollup watcher per
// environment. emptyOutDir is turned off because watch mode would otherwise
// re-empty dist/ on every rebuild, deleting the other environment's output.
//
// Watch builds are the dev channel by default (inverted icons, suffixed
// name; see scripts/dev-channel.mjs), so this dist/ can be installed next to
// the store build without the two being confusable. SUBSTANDARD_CHANNEL=release
// npm run dev opts out.
//
// Usage: npm run dev — then load dist/ unpacked and reload the extension
// in chrome://extensions after edits.
