OpenDPD Studio 2.2.13

PA output spectra now use larger, clearer legends above the plot. This makes DPD training and testing results easier to interpret on desktop and touch screens.

• Spectrum legends use 14 px text, with space for wrapped rows above the axes. Axis titles and tick labels are larger too. Adjacent signal-chain plots reserve the same space so their axes stay aligned.
• With DPD · PA model and Without DPD · PA model replace the corresponding “surrogate” legend labels. The PA output plot explains that a surrogate is the trained amplifier model: original input → PA model without DPD, and original input → DPD → the same PA model with DPD.
• Model predictions remain distinct from measured and synthetic dataset curves. The explanation and model labels are available in all nine interface languages.
• Touch layouts preserve each chart's legend size and spacing. Zoom, trace visibility, enlargement and native plot downloads remain available.

This release changes presentation only: stored PSD values, signal identities, training, metrics and exported source data are unchanged.
