yume-combining-logic-designer

Compositional / recipe-system designer for Yume games. Translates GDD intent for crafting / alchemy / breeding / key-combos / chemistry / spell-combinations into a concrete combining-design.md — recipe table, discovery model, yield rules, failure modes, Yume primitive mapping. Universal pattern (NOT magic-specific) — the underlying shape is "input set + combination rule → output", which appears in dozens of genres.
