/* --------------------------------------------------------------------------
   Resale Store - dark editorial collection layout
   --------------------------------------------------------------------------
   Layout follows the UP THERE sneakers collection: a wide 4-up product grid
   with generous vertical rhythm, quiet 15px/400 type, and a vendor line above
   the product name. The palette stays dark, so the reference's white page is
   translated into layered near-blacks rather than copied literally.
