- Refresh the specs snapshot with:
  `curl -sL "https://docs.google.com/spreadsheets/d/1jZWkkjewOuyNC9YzQ8y2d0pO1e4T7EBeysmQMPBVSOk/export?format=csv" -o data/itelescope-telescopes.csv`
- The CSV has multi-line cells (quoted); line count is not row count. Telescope rows
  start `T<number>,`; observatory header rows have an empty first column.
- Sensors are 16-bit ADC unless noted (T20's ASI2400C is 14-bit).
- Free scopes (30 min/day): T68 (Utah), T33 (Siding Spring).
- Minimum elevation limits come from the support article, not the sheet.
