What is this?

SPAs (React/Angular/Vue) own component state, routing, and render trees. jQuery owns DOM patching on server-rendered pages. Mixing without boundaries creates dual sources of truth.

Why should you care?

QueryVerse should not become a mini-React inside a jQuery soup without an explicit island strategy.

Result

What happened?

If you need client routing, normalized stores, and rich component trees, an SPA framework fits.
If you need progressive enhancement on Razor views, jQuery (or light vanilla) fits.
Avoid both manipulating the same nodes.
