On arrival with no ?preset=, www/src/routes/_app/create.tsx seeds the editor from localStorage via setDesignSystem(stored). usePresetHistory records that seed as an ordinary edit.
Failure: Undo is enabled the moment /create loads, and pressing it drops the user to factory defaults — a state they never edited from and never saw.
Fix direction: apply the storage seed without recording it, the same way time-travel navigations are excluded.
Found reviewing #511.
