Shift is the fine step on every number box, but on whole-number boxes such
as Feather the fine step was the step, so Shift did nothing. There it now
slows the drag four times instead. Pressing or letting go of Shift during
a drag carries on from the current value instead of jumping.
makeScrubInput in js/shared/scrub_input.mjs is the LoRA strength box's
interaction made reusable: drag the value to scrub (dead zone keeps
clicks clicks), click to type an exact value, chevron arrows step,
ArrowUp/Down step from the keyboard, Shift always means the fine step.
Values are quantized through one choke point, and edit mode re-asserts
itself a frame after the click because the graph canvas can steal focus
mid-sequence.
The gesture math is pure and tested (tests/scrub_input.test.mjs).
AGENTS.md and the brand skill record the convention - numeric fields in
pack panels use this control, never a bare input[type=number] - and
AGENTS.md also picks up the lab shared-code vendoring pull step.
