🎲 Each click rolls a fresh random build in that style — always complete, always conflict-free. Your current picks are replaced.
No conflicts found Check first — adds a warning (open the part for why) Won’t fit (open the part for why) Nothing selected yet — no data to judge ✓ Verified = interfaces & weight checked vs manufacturer spec; open a part to see whether its price is a confirmed MSRP or still a sample (else ≈ estimate) No ✓ usually means the maker doesn't publish the spec — not that the part is worse.

A green dot means no conflict among the dimensions we check — some parts publish no data, so it's not a guarantee of perfect fit.
