The nursery lands (stage 1 refuted, stage 3 proven); zipp.org goes up

The generational nursery's first stage is refuted by its own measurements before the third stage lands with a prover; the first landing page is committed the same day.

NURSERY_DESIGN.md was written when GC looked dominant; the ledger later corrected that ("GC is 2-12%, not dominant — B81 corrected" and "it is the COLLECTOR, not the allocator — pool built, measured zero, reverted"). Stage 1 of the nursery was refuted; stage 3 (82e454fa, 72cb640f) landed with a prover that verifies remembered-set invariants, ZIPP_NURSERY_VERIFY=1. The design document now carries a header calling itself historical. 0d124bf1, "feat: add Zipp landing page", is the first version of this site.
