photoshop_recipe_dodge_burn

One-shot dodge & burn setup: creates a 50% gray layer in Overlay or Soft Light mode for non-destructive light sculpting. Wrapped in a single undoable history step. Users often say: dodge and burn, sculpt light, lighten face, darken shadows. Use when: the user wants a ready-to-paint dodge & burn layer above the subject. Do NOT use when: the user wants automated retouch — this only sets up the paint layer; paint white (dodge) and black (burn) manually at low opacity. Do NOT use when: automated portrait smoothing is enough — use photoshop_recipe_enhance_portrait instead. Returns: { ok, summary, undo_history_states_consumed, details: { layer_name, blend_mode } }. Preconditions: active document with a raster-compatible active layer. Side effects: adds one "Dodge & Burn" layer above the active layer; one undo reverts.
