   Crow Messenger — autonomous flying crows that carry a rolled scroll in
   their feet. Click one and that scroll flies out and unrolls in the center
   of the screen; scroll the page or click the backdrop to dismiss (it
   catches fire from the middle, burns away and goes up in smoke, then a
   fresh crow flight resumes). CSS + GSAP + 2D canvas, no build step.
