   MANNKIND — engraved plates in the blue.   (2026-09-07 rebuild)

   No scroll engine. No camera. A normal document: full-screen plates stacked
   one per screen, each a white-line engraving floating in a deep brand blue
   with ONE immense light behind it. The only motion is a quiet fade as a block
   enters, plus hover. Everything else is still.
