photoshop_recipe_gradient_fade

One-shot gradient fade on the active layer mask: creates a reveal-all mask if needed, then paints a linear black-to-white gradient for soft edge blending. Wrapped in a single undoable history step. Users often say: fade into background, gradient mask, blend subject, soft edge fade, arka planı yumuşat. This applies a linear gradient on the layer mask channel — not a Gradient Fill layer. Use when: the user wants the active layer to fade into the background or layers below through its mask. Do NOT use when: the subject is not isolated — use photoshop_recipe_remove_background first. Do NOT use when: replacing the sky with an external image — use photoshop_recipe_sky_blend. Returns: { ok, summary, undo_history_states_consumed, details: { direction, start_pct, end_pct, mask_created, layer_name } }. Preconditions: active document with an active layer. Side effects: creates or modifies the active layer mask; one undo reverts everything.
