   Atlas — ZION skin (2026-09-23)
   Black-and-white "Zion ops" board wall with a planetary gear core.
   Everything here is scoped to html.zion, so ?skin=classic (or removing the
   <link>) restores the original look instantly. Light + dark via html.zion-light
   / html.zion-dark. Original UI tagged in git as biz-atlas-pre-zion-ui.
