 * Shared config for the two single-file IIFE bundles (`headless.js`,
 * `tests-bundle.js`). Both are self-executing chunks with no `import`/`export`
 * statements so they can be evaluated directly inside the Penpot plugin sandbox
 * (via `globalThis.ɵloadPlugin({ code })` for headless, or the UI "Reload"
 * button's `eval` for the tests bundle). They differ only by their entry module.
 *
 * `emptyOutDir` stays false so a `watch` rebuild of one bundle never wipes the
 * sibling outputs in the shared `dist` directory.
