Fitment and build notes

Vendor catalog record promoted for browsing. Final fitment, install dependencies, and shopper selection still require review before checkout.

For a lift, the last check is the complete Jeep setup: exact year/model/trim, doors, engine, lift variant, target tire size, wheel width and offset/backspacing, bump stops, flare/fender clearance, gearing, spare support, added bumper/cargo weight, and whether a shop is installing it.
