   Loaded LAST (after fonts.css, xzg(-en).css, overrides.css, woo.css).

   Goals
   1. No horizontal scrolling anywhere; nothing clipped at the edges.
   2. Header: one tidy row on a 320px phone — brand, language, cart, menu.
   3. The promo bar stops floating over the content on phones.
   4. Comfortable reading: fluid type, 44px+ tap targets, safe areas.
   5. Product / cart / checkout layouts that actually fit a phone.

   to two lines, was pushed past the left edge and the page scrolled
   sideways. Everything is now sized so the row fits from 320px up.
