Presets and templates
A preset is a reusable piece of text for one block; a template is a named set of (block → preset) choices. Built-in defaults are seeded and protected from deletion; you can create, edit, and save your own.
They let you capture a phrasing that works once and reuse it everywhere, instead of retyping the same instructions into every generation. Save a preset when an Expert-mode edit gives a good result, and build a template when a particular set of blocks suits a kind of song.
