ux v1.43.3: room gear discoverability, bigger metrics, touch tooltips take two

- 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

 # Changelog
 
+## v1.43.3 — 2026-07-27 (user feedback: discoverability and touch)
+
+- **Room settings were unfindable.** The gear added in v1.42.0 lived inside the
+  room label at 0.9em of its font and 60% opacity — a few pale pixels on a
+  normal plan. It is now a pill button "⚙ Room" of a fixed, readable size that
+  does not shrink with the card font, and it appears on **unnamed rooms too**
+  (that is where you name them). This also unblocks the font-size sliders,
+  which nobody could reach.
+- **Metrics line enlarged** from 0.62 to 0.75 of the room name — the reporter
+  could scale the name but the sensor line stayed unreadable on a tablet. The
+  per-room and per-space multipliers still apply on top.
+- **Touch tooltips, take two.** The `(hover: none)` guard was not enough: some
+  devices, skins, styluses and paired mice report `hover: hover`, so tips still
+  stuck under the finger. The card now also latches on the first touch/pen
+  pointer event and drops any open tooltip on touch.
