pub fn set_speed(scale: f32)Expand description
Stretch every catalog timeline by scale — 10.0 slows the 200ms pane
tweens to 2s, so a screenshot burst can sample the geometry frame by frame.
Configuration in code, like the rest of bezel: an app that wants this on a
setting, or hanging off its own theme, calls this from wherever that lives.
It used to read a BEZEL_MOTION_SCALE environment variable, which meant the
one knob in the library that no app could reach.
Clamped to 0.01..=100.0; a non-finite scale resets to 1.0 rather than
poisoning every duration with a NaN.
