Additional validation after opening PR:

• Re-read README.md and docs/README.md. README recommends validating with the HAT-P-32 b sample dataset.
• Cloned rzellem/EXOTIC_sampledata locally; confirmed 142 FITS files in sample-data/HatP32Dec202017.
• Re-ran python -c "import exotic": passed.
• Re-ran pytest tests/test_utils.py: 32 passed.
• Ran focused Colab validation against the first sample FITS file (OBSERVAT=Whipple Observatory) through exotic.api.colab.find() and make_inits_file(). Verified generated inits values:
  • Filter Name: CV
  • Obs. Latitude: +31.675467
  • Obs. Longitude: -110.951376
  • Obs. Elevation: 1268
  • Pixel Binning: 2x2
  • Secondary Observer Codes: MOBS

Full README sample reduction was also attempted with python exotic/exotic.py -red sample-data/inits-local.json -ov. It started the Complete Reduction routine but failed outside this change while LDTK attempted FTP limb-darkening grid access: ftplib.error_reply: 229 Extended Passive Mode Entered. That failure is in external LDTK data retrieval, not the Colab MObs metadata path changed by this PR.
