Case contract

Input operations configure character budget then append indivisible phrases [text,language]. Flush packs consecutive same-language phrases with one space while within budget. A phrase longer than budget is emitted alone intact. Language change always starts a new packet. Empty phrases are ignored. Break inserts hard boundary. Cancel removes queued phrases of one language. Returned packets are [language,text], queued phrase count and budget; flush consumes pending phrases.
