 - With the menu open, a click elsewhere closes the whole bar, and option changes made before a cancel aren't saved.
 - The toolbar doesn't take the capture lock: two bars can stack, and a capture started during the countdown makes the toolbar's capture fail.
 - The bar can cover a bottom panel, while the countdown pill sits above it.

+- [ ] Region: while dragging, a `W × H` label follows the pointer (physical pixels, same as the saved PNG), flipping near the edges.
+- [ ] Shift locks the dimension you move first; Alt grows from the centre; Space held moves the selection, and after letting go resizing continues without a jump; Space before a drag still switches to window mode.
+- [ ] `[capture] window_shadow = true`: window shots get a soft shadow following the rounded corners; preview, clipboard and file all have it.
+- [ ] Shots in quick succession play sounds 1 → 5 getting faster and brighter, then 6, 7, 6, 7 rising endlessly; after a 5 s pause it starts at 1 again. `valw __combo-demo` plays the whole sequence for tuning.
+- [ ] `[sound] enabled = false`, `volume`, `combo_reset_secs` take effect; the toolbar's Play sound option overrides the config; no `pw-play` → no sound, capture still works (warning in the log).
