## Hearthvale address chooser (docs/HOUSING_V2.md), UI v3 skin. Opened by the Hearthvale Gate in Aldoria (no house
## yet), the Lane Keeper in every lane, or "Move" in the Life window's Home tab. Left: the open lanes (neighbours, party
## friends living there); right: the lane plan - 4 rows x 5 plots on two streets, every plot a card (house number,
## owner + house level, NPC tenant, or "For rent"); pick one and press "Live here" / "Move here". All server commands
## (house_list -> "lanes" event, house_claim / house_move).
