> Large pull requests are hard to review, slow to merge, and prone to conflicts. Reviewers lose context, feedback quality drops, and the whole team slows down.

OK, yeah, I’m with you.

> Stacked PRs solve this by breaking big changes into a chain of small, focused pull requests that build on each other — each one independently reviewable.

I don’t get this part. It seems like you are just wasting your own time building on top of unreviewed code in branches that have not been integrated in trunk. If your reviews are slow, fix that instead of running ahead faster than your team can actually work.
