Pull request 100091 fixes a regression where a dynamic component rendered from the custom app file caused the page's server HTML to preload a chunk that returns a 404. The fix chunks those shared dynamic imports with the app file's own availability, and it also makes…

Second, development update timing. Pull request 99671 simplifies how hot reloading instantiates modules, cutting stack depth roughly in half for deep import chains — raising the failure point from around 800 levels to nearly 1,500 and approaching production behavior.
