The original re-times this movie to the song (the same frame sync the dancers
use): the 40-frame bob is one beat, so 60 fps only at 90 BPM.

The original advances the movie at 120 Hz, so the bob ran at half speed, and it
paints the crowd after the bottom band, not under it.

The original's random pool only holds fever_effect1 and fever_effect2;
fever_effect0 is a single figure parked off-screen, so picking it showed an
empty crowd at 魂 max. Drop it and pick from the two real crowds.

The 魂 max crowd was two flattened PNGs, so every figure sat at one fixed
position, the turtle/shiba groups lost their depth order, and nothing moved.
The crowd is now data-driven: one texture per crowd group
(background/fevera_N) plus a per-frame display list
(bg_data/fever_anim/f_N.lua) covering the rise, the loop and the fall, replayed
by bg_objects/fever_anim.lua at 60 fps. Every group bobs and squashes on its
own phase and layers exactly as authored; the base of the crowd lands on the
band. Three crowds are shipped; the old flat overlays stay as a fallback for
skins without the data.
