What happened

The badgeTone function ran and returned a string that is not one of the theme's tone names. Returning null or undefined is the supported way to say "no tone" and is not reported; an unrecognised name is, because it is almost always a typo or a raw colour.

The fix

Return one of the tone names in the message, or null for an untoned badge. Colours come from the theme's tokens, not from the tone value.
