Value Readout

A caption over a big tabular-monospace number, with its unit beside it and an optional qualifier underneath — the REDUCTION / −14.0 dB element every meter-bearing face grows, made once. Tabular figures so a live value does not reflow as its digits change; the unit as a separate muted element so the eye reads the magnitude first; and, crucially, a missing value prints an em dash rather than a zero, because a meter with no source showing 0.0 dB claims a measurement it never received. A real zero still prints as zero — that negative case is pinned. The note line is where "predicted", "reference pattern" or "no tap from this host" goes, and an accent recolours the value alone, never a placeholder.
