// in the app hardcodes where it's hosted. Locally (dev/build/preview) it stays at root.
//
// `assetsDir` is namespaced to `website-assets/` (not Vite's default `assets/`) so the
// build can be overlaid onto the MkDocs `site/` output without colliding with MkDocs's
// own `/assets/...` tree. Public files live under `public/static/` for the same reason —
// the HTML entries provide the landing and product routes on static hosting.
