+ * The harness is the static counterpart of src/dev-entry.tsx :
+ * read URL query params, mount() Solar against the requested Orion
+ * endpoint with the requested mode/token. Inlined into the HTML so
+ * the host fetches a single file plus the already-bundled solar.js.
+ *
+ * Run as the second step of `npm run build` after `vite build`.
