# Digital Twin ("Pick My Brain") page
# Uses tokens from this-site.css. The card FRAME (header, page
# copy, buttons) carries the site's brand — the chat PREVIEW
# content (avatar, bubble, chips, input bar) stays visually
# faithful to what Delphi actually renders, so there's no jarring
# switch when a visitor clicks through.

/* Override .hero's 100vh + vertical-centering — this page's content
   is taller than the homepage/boxercise hero, so centering it inside
   a fixed viewport pushed the top of the card up under the sticky
   header. Flow naturally instead.
   The fixed header's own height changes at the lg breakpoint: its
   140px logo is `d-none d-lg-block` (hidden below 992px), so the
   header is ~94px tall on mobile/tablet but ~164px at lg+ once the
   logo shows. Clearance below matches each case with a margin. */
