Quoted Fields

When a field contains the delimiter (or newlines, or quotes), wrap it in ":

name,description,tags
Alice,"web developer, backend",python
Bob,"says ""hi""",java
Carol,"multi
line",none

• "web developer, backend" — comma inside is preserved.
• "says ""hi""" — escape " by doubling: "".
• "multi\nline" — newline inside the field doesn't end the row.

Parser logic:

Key insight: a " ENDS the field unless followed by another " (an escape).
