## What? Rename `experimental.dynamicIO` to `experimental.cacheComponents` across the Next.js codebase. ## Why? We're going to be merging the functionality of the `ppr`, `dynamicIO` and `useCache` experimental flags into the singular `cacheComponents` flag to reduce complexity of the codebase and simplify adoption for users wanting to experiment with experimental features. ## How? - Renamed the configuration option from `experimental.dynamicIO` to `experimental.cacheComponents` - Added deprecation handling with automatic migration for the old option name - Updated all documentation, tests, and internal references - Updated Rust code in SWC transforms and Turbopack - Maintained backward compatibility with deprecation warnings NAR-158

This page renders two components. Both call a simulated IO function

wrapped in `unstable_cache`.

With PPR this page should be entirely static because all IO is cached.
