The operator-facing warning for an allocation whose N exceeds BUS_INPUT_CAP, or
undefined when it fits.
Above the cap busInputCount sizes every bus to min(N, cap), so the inputs past it
exist as strips but can send to no bus at all — the single-tier mixer tree has no slot
for them. That is a real, silent loss of the console's top end, so it is named here rather
than left for the operator to discover during a gig.
