/*
  v/base.css: the shared floor under every finished design variant (A to H, excluding removed B/E).

  WHAT IS HERE
    Reset, accessibility helpers, buttons, the merchant finder (search, chips, map, list cards),
    placeholder badges, toast, scroll reveal and the floating Design switcher.
  HOW A DESIGN USES IT
    Each design (v/a.css ... v/e.css) sets the tokens below on :root and then adds its own layout and
    decoration. Change a token and the finder, buttons and switcher follow. Nothing here is a look
    on its own: with no design file it would be plain.
