   NOVA SAKI — launch countdown
   Design tokens and layout follow design_handoff_countdown_landing/README.md.
   The planet anchor percentages are measured against the background art;
   if the art is ever re-exported with a different crop, they must be
   re-measured or the clock circles drift off the painted planets.
