A row of toggle chips below the filter box — one per pql ticket type,
ordered large→small (Initiative, Epic, Story, Task, Bug), each with its
TicketTypeColors dot + border. Single-click toggles a type; double-click
isolates it (chart-legend solo, fully reversible); disabling the last
enabled type snaps all back on so the list is never blank. ANDed with the
text filter; all on by default, nothing persisted.
One GestureDetector owns both onTap + onDoubleTap so Flutter disambiguates
single vs double. Wireframe updated + approved.

Bug / Ticket / Epic / Initiative toggle chips at the top of the tickets
panel, all on by default. Single-click toggles a type; double-click solos
it (chart-legend pattern), double-click again restores all; last-off
resets to all-on. Filed under the UI epic T-276 with a Frame0 wireframe.
