/* ===========================================================================
   Shared shell for the demo artifacts.

   Both demos are AI-generated one-shot outputs, but they should read as one
   product: same palette, same chrome, same "click a thing -> evidence appears
   in the right rail" interaction, same responsive rules.

   Layout contract
   ---------------
   .demo-nav      cross-links (talk index + sibling demo)
   .panel         header / controls / stage / footer blocks, hairline joined
   .facts         the numeric scoreboard strip
   .split         main visual (left) + .rail inspector (right)
   .rail          scrollable evidence panel, sticky on wide screens

   Scaling rules
   -------------
   - one container width token, applied to header AND body so nothing is
     full-bleed against capped content
   - every grid child gets min-width:0 so long mono strings cannot force the
     page wider than the viewport
   - the SVG stage keeps the diagram's aspect ratio instead of stretching to
     the sidebar's height, which is what produced the large empty gap
   - below the breakpoint the stage scrolls horizontally at a legible minimum
     width rather than shrinking the labels into unreadability
