   QuickDesk ATU — single-file page styles
   Source of truth: combined 6 pages in D:\project\QuickDeskWebsite-atu-8-25\
   part-1 → page-01 (Hero)
   part-2 → page-02 (Product advantages)
   part-3 → page-03 (Connect. Acquire. Monitor. — anatomy + hotspots)
   part-4 → page-04 (AI agent workspace — Tell ATU what data you need)
   part-5 → page-05 (Collect → Configure → Deliver — architecture flow)
   part-6 → page-06 (Practical ways to put ATU to work — applications + LinkedIn CTA)
   Scope: styles applied inside <main> on /:locale/atu/ pages. All classes are
   atu- prefixed to avoid collisions with site-header / nav / footer in base.html.
   Videos are skipped (videos/atu is empty); poster images used where appropriate.
