rofi hard-fails on a duplicate keybinding and reports it in a GUI error
dialog, not stderr — so 05bab55's Left=Back killed every menu entry
point on a real session while passing all stubbed tests. Rebind
kb-move-char-back to Control+b in both rofi_menu copies (menu + vpn).
V3 on the migrated T14s: error dialog reproduced with old flags, menu
renders with fixed flags. Journal + two PROPOSED pitches (EasyEffects 8
tray icon, parallel fingerprint/password PAM).
