/* The parts marketplace. Loaded AFTER public.css and never instead of
   it: every structural class the parts pages use (.public-page,
   .public-header, .public-hero, .public-grid, .public-vcard,
   .public-sublink, .public-browse-section, .public-footer) is the car
   marketplace's own, so the two sites are the same site. Item: "same
   design as the car site".

   What is here is only what a parts shop has and a car marketplace
   does not: the shelves, the counter, and a buyer's own request page.
   Every colour, radius and font below is a theme.css token, never a
   literal, for the same reason public.css gives. */

   has room to teach what can be typed into it. */
