   PURE Window Bar — browser-style strip of open "windows" (sections)
   that sits flush on the top edge of the white workspace window.
   window.PureWindowBar.mount(el, opts) -> controller
   All classes namespaced .pwb-*. Light surface only (lives on white).
   Active window = solid Gold 500 tab; unselected = white, gold bottom rule (the
   window's gold top edge) — no outline.
   When windows overflow (desktop: no width left · mobile: >5) a narrower
   "See all extra windows" button collects the rest into a dropdown.
