CTA plots: publication dpi=300; flatten singleton plot folders (apd1_vs_tmb.png flat + --flatten pass); rename CTA-specific-9mer 'payload'->'load'; log-y companions for the 9mer load (incl. aPD-1-colored); drop the sweet-spot band on the aPD-1 axis. Plot-script only; DATA_VERSION unchanged. See #367.
