   ai-intelligence.css — Mastery Logistics Systems
   AI & Intelligence page-specific styles.
   Global styles live in style.css.
   Desktop styles first. Mobile overrides at the bottom.

   COMPONENT REUSE:
   - .banner — slim warm band component.
   - .feature / .feature--reverse — standard alternating two-column
     feature block.
   - .cta-banner — standard closing CTA.

   NEW COMPONENTS INTRODUCED HERE:
   - .video-placeholder — distinct from image placeholder; includes
     a copper play button overlay so it reads as video, not image.
   - .ai-hero — hero with video on the right side.
   - .chat — Leo chat visual used inside feature blocks (Sections
     3 and 4). Dark panel with user/bot message bubbles. Bot
     responses can include an embedded confirmation card.
   - .cards2 / .cards2__card — 2-card warm block for "How Leo
     works for you" with dark chat-style visuals on the cards.
   - .ci-vis — Custom Instructions card visual (user setting +
     Leo acknowledgement).
   - .mem-vis — Memories card visual (list of remembered defaults).
   - .multi-agent / .leo-stack — dark section: request bubble into
     the Leo pill, two-way connector, MasterMind chip container.
   - .cards3 — 3-card warm block for "Open by design" / Beyond
     Leo — three equal cards.

   PAGE STRUCTURE:
   1. Hero (dark, two-column with video right)
   2. Slim banner (light warm)
   3. Find Information feature (white, chat right)
   4. Take Action feature (white, alt — chat left)
   5. 2-card How Leo Works (light warm)
   6. Multi-agent forward-looking (dark)
   7. 3-card Open Platform (light warm)
   8. CTA banner (dark)
