Subject: [PATCH] Research Gallery dev fallback: the manifest at the public
 root first, so the dev server serves children as the raw build

Reached as /public/<tree>/, the dev server treats a built bundle as source and
injects an import into its IIFE, so a child loaded as a classic script threw
"Cannot use import statement outside a module" on the staging page. The root
path is tried first; /public/<tree>/ stays last, for a plain static server.
Built trees resolve the manifest before these fallbacks and are unaffected.
