Required: name, latitude, longitude — lat/lng as decimal degrees.

Optional: color (hex), description, personal_notes (or note), tags, image_urls, video_urls, links.

Commas: any field containing a comma must be wrapped in double quotes — e.g. "bar, cafe".

Lists: tags, image_urls and video_urls are comma-separated inside one quoted field; links are comma-separated Label::URL pairs.

Lines starting with # are ignored.

A good entry has a clear name, accurate coordinates, at least one tag, and a one-line description.
