3	* Asks why, on the way out.
4	*
5	* The moment someone deactivates is the one moment they definitely have an
6	* opinion, and it is the last one we get. So we ask — but the rules are strict,
7	* because this pattern is easy to abuse:
8	*
9	* - Deactivation is never blocked or delayed. "Just deactivate" is always one
10	* click away and is the default if anything goes wrong with the dialog.
11	* - Nothing is transmitted from here. Choosing a reason opens the feedback form
12	* in a new tab with that reason pre-selected; the user still decides whether
13	* to send it.
14	* - It appears once. Dismissing it, or deactivating without answering, sets a flag.
