   ATLAS Sync public landing site — atlassyncapp.com.
   The same approved Command Deck token vocabulary (web/command-deck/styles/
   deck.css), scaled for marketing typography. Deliberately a single dark
   theme: the product IS a dark trading console, its screenshots composite
   onto this ground, and the page commits to that world — every background
   and color painted explicitly. One warm amber accent; ink surfaces
   separated by hairlines, never drop shadows; monospace for data.
