/*
 * THE NUMERIC FIELD, in its two presentations. The BARE BOX is the same control
 * surface as a text field: the ROOT carries the edge, the ground and the ring
 * (§2.3), the input only the digits.
 *
 * A `stepper` spends no surface at all: the two discs are the edges and the figure
 * between them is the same field with its box surrendered. 32 and 56 are the
 * stepper's own measures — a disc between `IconButton`'s `md` and `lg` rungs, and
 * a figure slot a four-digit quantity does not shove the + out of.
