/* Tabs and segmented filters, drawn as one segmented track (polish pass): the options sit in a single sunk
   well, the selected one is a raised tile inside it. Before, each option was its own bevelled box and the
   pick was a shiny brass plate, so a row of six read as six buttons fighting. Markup and ARIA are unchanged:
   .tabs/.tab     role="tablist"/role="tab": switches what one panel shows. Keyboard: arrows, Home, End
                  (bindTabs() in js/lib/ui.js).
   .seg/.seg-btn  filter buttons with aria-pressed (shop categories, gender). Several may sit side by side.
   .plates/.plate the same look under the new names, for new markup (aria-selected, aria-pressed or aria-current).
   On narrow screens tabs scroll sideways with proximity snap instead of wrapping into a pile. No overscroll
   containment: at either end a gesture passes on to the page, so a strip never traps the wheel or a swipe. */
