// Convert a SeedDraft into a ProseMirror JSON document the user lands on in
// the editor. After the pivot the prose is canonical; the analyze pipeline
// derives taxonomy / glossary / model / requirements from it on demand.
//
// We use a deterministic template (not an LLM) — fast, predictable, and the
// user is going to keep editing anyway. Section structure mirrors the seed
// fields so the analyze passes have clear hooks.
