/* G-TECHPRO, look B "Copper": shop pages (collections, product, basket, search).
   Everything sits on the dark board: footprints are dashed copper (.fp), connectors are a solid copper outline, groups of
   facts are IC chips (.ic), grades are battery cells plus a name. Headings are Big Shoulders (base), the rest is mono.
   New classes only: nothing from base.css is restyled here. Prefixes: shop- list, f- filters, ask-/req- requests, sig- cross
   links, pdp- product, gt- grade table, cart-/cr-/ce-/sum- basket, search- search. Spec: /DESIGN-COPPER.md */
