 * define call's stack gives the generated positions to map through it. This
 * module only records those positions; resolving them takes fetching the
 * page's scripts, which is the host's job (the extension's panel does it).
 *
 * Only defines made after {@link installDefineSites} runs are seen, so it has
 * to run before the page's own scripts: the extension injects it at
 * `document_start`.
