The Window Translucency slider moved in fixed 5% jumps, so a 0-100 lever had only 21 stops packed into a 160px control -- and arrow-key nudges skipped 5 at a time. The settings that are actually readable live at the low end, so the coarse step made most of them unreachable. Step in single percent, and hoist the bounds into named constants beside the atom that owns them, mirroring PET_SCALE_MIN/PET_SCALE_MAX so the control and the clamp read from one source.
