The GAIN control descriptor for a preamp that declares range — the head-amp answer to "how
far does this knob go, how finely, and may I move it?".
Read the range through headAmpGainRangeOf(capability, pad) (pad-aware, one reader) and hand
it here; this function deliberately does not take the capability itself, so the same builder
serves the desk-owned gain (which has no capability) without a branch on kind.
