// An act that was stored as text and is compiled where it runs (designs 062, 277).
//
// The source names `@aweftjs/ui` the way a file on disk would, so the transform's text pass finds
// its literals like any other file's. A module compiled at run time has no bundler to resolve
// that import, so `compile` rewrites the specifier to a bridge the host provides: the package's
// own URL in Node, and in a browser a module the entry made from what its bundle already holds.
