Add a "Report Language Error" button in the Lumo chat interface that lets users flag language issues directly. After clicking, users choose a category:

Strict — Pure nonsense/incorrect term. Generates a corrected, academically accurate response.

Synonym — Suggest an alternative word/phrase and context where it fits better. Helps Lumo understand nuance, register and topic-specific synonyms.

Humoristic — Witty alternatives and wordplay. Helps Lumo learn humor and puns in the local language (especially useful for users with a "Casual/Cheeky" Lumo personality).

This feeds into Proton's language improvement pipeline, helping Lumo and Scribe produce more natural, localized output — especially for smaller languages like Norwegian, Danish, Swedish and Finish.

Use case: When Lumo says "hundkur" instead of "hundkoja," the user flags it as Strict. When Lumo misses a pun opportunity, the user flags it as Humoristic — and Lumo gets funnier over time.
