- internal/playground → internal/plugin-gallery; playground-smoke → plugin-gallery-smoke;
generate-spa → generate-gallery (scripts: gallery, smoke:gallery; smoke:playground stays as alias)
- generate-gallery exports renderGallery(model, { mode }) — the dev plugin serves the same page
at / from the discovered registry (dev mode imports the dev entries, ladder popovers on);
the build writes public/index.html from the manifest (byte-identical to before)
- Docs and probes use the gallery vocabulary
