+## 2026-07-12 — tray menus truly fixed: counter-rules must live in waybar.css (8eb672b, 72e53e2)
+- **Task:** Bernardo: icons still missing in the REAL nm-applet menu.
+- **Did:** e8658fe's gtk.css cure worked in a plain GTK app but not in
+  Waybar: Waybar adds its provider at GTK_STYLE_PROVIDER_PRIORITY_USER
+  too (src/client.cpp) and wins the tie in practice (GTK 3.24) — proven
+  by repro at priority 900 matching the live menu exactly. Only rules in
+  the SAME stylesheet out-specify its `*`, so every waybar.css now
+  carries a menu block after the reset: arrow 16px, check/radio 14px,
+  separator 1px, `menu, menu *` font (labels are matched directly by
+  `*`, inheritance never applies). D-Bus GetLayout first proved
+  nm-applet exports per-network icon-data.
+- **Verified:** **V3 on the real menu** — opened nm-applet's tray menu
+  via wlrctl virtual-pointer clicks, grim captures: arrows, checkmarks,
+  separators, Inter labels, Pica's icon, and every network's signal icon
+  in the Available-networks submenu. Bar pills intact. NB: cursor-warp
+  hover does not open GTK submenus (no motion events) — click the item.
+- **Pending:** nothing for this item.
+- **Next suggestion:** #89 slice 2 — the override-icon layer.
+
 ## 2026-07-12 — #90 correction: scoping regressed the bar; USER-priority cure (e8658fe)
 - **Task:** Bernardo reports ac7e6bd broke Boreal's bar + icons still missing.
 - **Did:** Two lessons. (1) `window#waybar *` carries id specificity, so
