Covers the two-phase response mechanism (static shell from CDN + streaming dynamic holes), Suspense boundary placement rules, PPR's interaction with the Full Route Cache, Suspense fallback design for zero CLS, measured TTFB/LCP outcomes, comparison against ISR+CSR and full SSR, known limitations, and the decision framework for when PPR is the right architecture choice.
