- the room gear became a fixed-size pill button (was 0.9em/60% opacity
inside the label — invisible in practice, field report); shown on
unnamed rooms too, which is where you name them
- metrics line 0.62em -> 0.75em (unreadable on tablets)
- tooltips: latch on the first touch/pen pointer event instead of
trusting (hover: none) alone; any touch drops an open tip
- smoke_feedback_v2.mjs; docs same-commit
