// Build entry point. Run via `bun run build` (or transitively via
// `bun run lint` / `package` / `start`).
//
// Output: a self-contained `dist/` directory that web-ext consumes as its
// sourceDir. The bundler inlines `vendor/qrcode.js` into the popup script
// (via the ESM import in popup.js), so the published extension is one JS
// file plus the static HTML/CSS/icon/license assets.
//
// Anything outside `dist/` never ships, so this script is the single source
// of truth for "what is the extension."
