The 2023 client replaces its unlocked-item set with every list it
downloads (OutfitManager clears and refills it) and never merges its own
default list, so the server has to include the free
default_unlocked_variants items. v4/items only returned the player's
inventory, so items like Beard Close showed as buyable.
- v4/items returns the player's items plus the 239 default items, deduped,
with room kept for them under MaxUnlockedItems
- defaultunlocked returns the default items before login
- lockeditems never reports a default item as locked
