aws.internal._lower_block

(internal) One content block -> its Converse `ContentBlock`, or null when it lowers to nothing. Converse takes every media kind in a conversation message; a tool result carries `text`, `image`, `document` and `video` but has no audio member, so audio in a result degrades into a user turn after the run of results (`_lower_journal`); system content is text only (`_prompt_system`).
