"""Showcase tinymfv's plotting on a real steering run.

Consumes a steering-lite `run_allinstr_showcase.py` output dir (one calibrated
activation-steering vector administered across every instrument over a signed
c-sweep) and renders the SAME two figures for every instrument, uniformly:

  - map  : ipsative culture map (PCA), AI coherent +/-c path vs the human cloud.
  - range: per-factor range, AI base + coherent +/-c path vs the human society strip.

Ordinal instruments read <name>_profiles.csv. MFV reads mfv_profiles.csv and is
projected into z-scored relative-emphasis space, because its nominal foundation
probabilities cannot share a raw axis with 1-5 survey scores. It still goes
through the same plot_ipsative_pca / plot_range functions.

cs are SIGNED multipliers of the calibrated coefficient C (0 = base). The public
README plots show the coherent path: c=0 plus each +/-c row whose tinymfv answer mass
stays above the requested fraction of base. Incoherent rows are dropped.
