+All root and page entries are bundled in one esbuild build. If ten pages import the same package or local component runtime, esbuild can emit that dependency once as a shared chunk. Import-only page wrappers are collapsed after bundling, so generated pages link directly to the chunks they need instead of loading a `page-N.js` file that only re-imports the same chunks.
 
 `webui-press build` minifies bundled JavaScript. `webui-press serve` skips minification for faster rebuilds during local development.
