   Pep Research -- order request (checkout.html). Not a store checkout: the
   customer submits an ORDER REQUEST; Pepvela reviews it and sends payment
   instructions. Navy foundation, glass panels, compact technical type, the
   locked palette. Desktop: the form left, a sticky order summary right.
   Phones: one column -- a collapsible summary first, the form, then submit.
