* We extend Math.random() during builds and revalidates to ensure that prerenders don't observe randomness
* When cacheComponents is enabled. randomness is a form of IO even though it resolves synchronously. When cacheComponents is
* enabled we need to ensure that randomness is excluded from prerenders.
*
* The extensions here never error nor alter the random generation itself and thus should be transparent to callers.
