/**
 * The positions the mask left for the engine to fill that came out at ZERO —
 * values that are declared and can never be drawn.
 *
 * A mask shorter than the list is legal on purpose: what is left over goes to
 * the positions nobody wrote. `value="a,b,c" percent="30,40"` gives `c` the
 * remaining 30, which is the whole point. But when the written shares already
 * total 100 there is nothing left, and `c` silently stops existing —
 * `percent="50,50"` over 300 rows came out 150 `a`, 150 `b`, no `c`, and
 * `check` called the config valid.
 *
 * A zero the author WROTE is not reported: `percent="50,0,50"` says "never this
 * one" in as many words, and answering a clear statement with a warning is how
 * a gate teaches people to ignore it. Only an inferred zero is a surprise.
 *
 * Call it after `expandPercentMask` has succeeded — it assumes the parts parse.
