 3/// `profile set` — unlike every other filter or edit in the app, `--link`
 4/// replaces the whole set rather than appending, so every link the form
 5/// wants to keep is sent on every save. The form is always seeded from
 6/// the current profile, so every other field is also sent every time,
 7/// including empty ones: `--description ""` clears, omitting the flag
 8/// would leave the old value alone.
