Add a thin colored strip along the bottom of the spectrum (above the ruler) showing the QO-100 narrow-band transponder bandplan: mode segments (CW ONLY / NB DIGI / DIGI / SSB / MIXED MODES) plus the three beacons (CW / PSK / EXP) as muted-red cells at their ranges. - New unit BandPlanOverlay.pas (TBandPlanOverlay), modelled on VfoOverlay: content rendered once into a cache bitmap, per-frame cost is just a constant-alpha composite (CPU) / one textured quad (GL). Cache invalidates only on view change (center/span/width) so it idles while the QO-100 downlink display is static. - Wired into both render paths: SpectrumView (CPU composite) and SpectrumViewOpengl (texture, re-uploaded only when dirty). - MainForm: SetView fed from SyncSpecViewFreq; visibility gated by InQO100 (Pluto + full-duplex transponder), like RX MUTE / BEACON. - DPI-robust: strip height scales with Screen.PixelsPerInch and the font height is tied to the strip height (not point size), so labels always fit at any Windows scaling. - Segment/beacon frequencies and colors are a single editable table.
