+- An invite may carry its own mail: `invite: { group, mail: { subject, body } }`. Every field of the form is a placeholder besides `{name}`, `{link}`, `{expires}` and the rest, and a date and time (`type: datetime-local`) is written out in words ("tirsdag 6. oktober kl. 15:00"). The words and the form are kept with the invite, so sending it again sends the same mail. This is for a desk that invites someone to a conversation at an hour, not into a group for good.
+
 ## 0.6.14 (2026-10-01)
 
 - Less room above the wordmark: 1.75rem, 1.25rem on a narrow screen (it was 4rem). The space was kept for who is here, which now sits on the wordmark's own line, and on a tall, narrow screen it read as dead space.
