A user without the AI capability could not get rid of the floating
"Uppgradera för att använda {namn}" pill: it had no dismiss of its own,
and closing the paywalled agent sheet just brought it back, leaving a
wide overlay pinned in the bottom-right corner (reported by a user via
Discord).
The pill now carries an X segment (non-payer, fresh state only) and a
non-payer closing the agent sheet counts as the same dismissal. Both
hide all floating assistant UI for the rest of the browser session via
sessionStorage; a new session shows the pill full-size again, so the
conversion surface is muted per session, never silenced permanently.
Payer behavior and the collapsed-session handle (the only way back to a
minimized conversation) are unchanged.
