/*
 * N FIXED CELLS, EACH INDEPENDENTLY ON OR OFF, sized to ride inside a register
 * row. The gap is tight on purpose: the cells are one object — a week, a band,
 * a set — and a chip-row gap would read them as separate controls.
 *
 * The ON cell is an EDGE, not a ground, and the same edge a chip wears: a ground
 * is the row's language and these are controls, so painting a selection as a
 * fill makes two altitudes say the same thing in the same paint. The second
 * pixel is an INSET shadow, because a border would grow the box and shuffle the
 * whole strip the moment a day was picked.
