+### 90. Fix missing submenu arrows in nm-applet `[stuck]`
+**Context:** In Papirus, `pan-end-symbolic` is missing, causing `nm-applet`'s submenu indicator (e.g., "VPN Connections") to be completely invisible.
+**Attempted fixes (2026-07-11):**
+1. Bundled SVG with `-gtk-recolor` (failed due to GTK constraints).
+2. Bundled SVG with static Nix palette colors (failed).
+3. Added `.context-menu` specificity overrides for Waybar SNI tray menus (failed).
+4. Mapped to native `-gtk-icontheme("go-next-symbolic")` instead of bundled SVG (failed).
+**Next steps:** Needs a fresh look. Possibly `dbusmenu-gtk3` drops the arrow entirely or uses a custom widget structure.
