/* =====================================================================
 * The currency switcher a customer sees.
 *
 * A small button in the header — an exchange mark and the current code —
 * opening a dialog with the currencies this shop can honestly price. It is
 * deliberately quiet: a shop that sells in one currency to almost everyone
 * should not have a currency control shouting at every visitor.
 *
 * Everything is scoped under `.fils-*` and uses its own custom properties, so a
 * theme can restyle it by setting three variables rather than fighting
 * specificity.
