## Housing v2 P3 flower market window (docs/HOUSING_V2.md), UI v3 skin. Florist Posy on every lane plaza buys crops +
## flowers and sells crops, base / hybrid flowers and base-colour seeds, for gold. Prices drift every day (server/garden2.gd
## mult(): the same for everyone): each row shows today's price, the change since yesterday and a 7-day sparkline, so
## you can stock up on poor days and sell on great ones. Every button is a server command (market_sell / market_buy).
