Closing a folder (もどる) had no wheel motion at all: the fly table only
covered the open leg (clip f27..150), fly_offset only ran for kind "open", and
the engine's 166 ms fade took the song boxes and the back board out right
after the press -- the cabinet keeps them solid until they fly out (f184..204)
and the board furls (f205..217).
- anim/wheel_decide now spans f27..255 (open leg + `return` leg, straight from
the cabinet clip); fly_offset plays the return half on the close leg: song
boxes fly out, wait off screen across the swap (f219) and the genre boxes
fly back in f234..254. f255 re-bases the clip, so the leg stops before it.
- The engine's box fade is ignored during the pre-swap half of the close leg
(box_fade); the clip channels already drive the back board's title fade and
furl.
Verified with captures: press -> boxes stay -> contents fade / boxes fly out ->
back board furls -> genre board unfurls -> contents return -> boxes fly in.
