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