 * Render the canonical sw.js for a product (`version` defaults to `v1`).

 * NOTE ON `version`: bumping it invalidates every cache on activate, and it is
 * also what forces an already-installed service worker to be replaced promptly.
 * A push/notificationclick change only reaches installed clients through the
 * hourly `registration.update()` poll unless the version is bumped
 * deliberately, so bump it in the release that enables push.
