LLM instruction text for a TTS provider, or undefined when it has no markup dialect.
Each markup-capable provider gets its own expr instruction block — shared marker syntax,
but only the types and label vocabularies that provider actually supports;
convertMarkup lowers the markers to native syntax. Expr is the only dialect the
LLM is ever taught. When steering disables a non-verbal sound, its labels (and any
example demonstrating them) are omitted from the block entirely rather than advertised
and then revoked.
