   - Laptop: centered, back layer (largest footprint)
   - Tablet: portrait, front-right, overlapping laptop's right edge,

   - Phone:  portrait, front-left, overlapping laptop's bottom-left,
             extending below the laptop
   - Rocket badge: sits inside the composition, right of the phone,

                   the empty gap.

   on Tailwind arbitrary values like w-[78%]) because the laptop-screen
   is aspect-ratio + absolutely-positioned content, so it has NO intrinsic
   width. Without explicit width the laptop collapses to 0px.
