-----------------
INTENT text <-> 3-field form conversion.

The backend hands us ONE string with three headed sections. We split it into
three editable fields and MUST rebuild the exact same "Problem: / Objective:
/ Additional Context:" shape before sending it into the search graph -- its
prompts assume that literal structure.
