   Sequence (~2.6s):
     0–250ms   corner HUD markers fade in
     100–800   outer orbit ring draws
     350–1150  inclined orbit draws
     700–1200  core appears + pulse loop
     900+      electron starts orbiting (loop)
     1000–1700 wordmark letters reveal (50ms stagger)
     1100–1900 status feed lines reveal sequentially
     1100–2500 progress bar fills + scramble counter
     2400      stage fades out
