"""Build the Aureon sky map — the harmonic sensors, pointed at the sky.

Reads the committed real sky data offline (NASA Exoplanet Archive host stars with
RA/Dec + the DE440 planetary ephemeris) and maps φ-structure across the sky through
the **unchanged** phenolic engine, rendering an RA/Dec heatmap PNG. Two lanes:

  Stellar   — host stars binned by RA/Dec, each folding its Wien colour (st_teff).
  Planetary — DE440 planets painting their orbital-motion tones along the ecliptic.

Offline by default (committed cache + committed ephemeris). ``--fetch`` refreshes the
NASA cache from the keyless Exoplanet Archive TAP first. Verdicts are printed exactly
as the engine returns them; nothing about the engine is modified.

Run:
    python scripts/validation/build_sky_map.py --both --out sky_map.png
