"""ioby WebsiteBench offline clone.

Public pages follow anonymous archival captures from 2026-08-24.  Donation,
account, recovery, favorite, and recurring-plan behavior is an explicit local
simulation because the observed source was closed and exposed no usable live
transaction flow.  Runtime requests are same-origin and never leave the clone.
