- Snap points are detents in drag distance (snapPixels, default 24): the
value holds at the point, then continues, so no value is skipped.
`snap` is removed in favour of `snapPixels`.
- The dashboard's own hover haptics are muted during a drag, so only the
value's ticks and detents are felt.
- Longer drag per step by default: 120 px per 1.0 in the menu, 60 on the
bar button (step stays 0.05).
