Number Field

A compact numeric input on Base UI's NumberField with optional steppers and an optional Base UI Slider sharing its draft. One onValueCommitted per gesture (Enter, Cmd/Ctrl+Enter committed before any enclosing shortcut sees the key, blur, a stepper, a slider release, an arrow key), clamped or null when cleared; Escape reverts a pending draft and stops there. layout="row" is one 28px inspector line (flexible slider, 44px value); ghostValue draws a default as a tick where an unset thumb parks. Heights through the control-height variables. The draft and commit rules sit in a pure core beside it.
