Five sites hardcoded "#cacccc" or "JetBrainsMono Nerd Font" as the fallback when no bar context was available. Those magic strings are the *current* palette defaults — they diverge silently when the theme changes. Bind to the Color / Style singletons so the fallback tracks whatever the theme says the foreground / monospace family should be. Color.qml itself keeps the literal "#cacccc" — that's the seed value the singleton is bootstrapped with before the theme loads.
