   floor are the two refusals, and because the probe emits `::clicked` straight at the
   widget it reaches the handler even when the button is insensitive, so `add above 0` there
   must leave `rows=` and `traces=` untouched rather than growing a ninth row.
+- `header: window_button_w=W label_w=L bar_w=B` (stderr, once a second) — **`W` must be
+  a small constant and must not track `B`**: the window control is a header-bar child,

+- **The session layout round trip** (`~/.config/udpscope/<host>_<port>.toml`) — run once

 - `badge frames: lit=L dim=D idle=I` — the activity badge's phase per frame. Over a run
