/* ==== Sable app styles (production-shaped) ==============================
   One orb on solid black, rendered once at 180 px. Its places are
   transforms of one wrapper (only transform moves):
     centre 144 · the entrance and Home are the same place
     forward 180 · higher, clear of the iOS passkey sheet, for messages
   Words form beneath it. Motion follows WAYFINDER Connections round 7. */
