xsl 5fbc03a6df feat: 接口12/接口2 发际线重绘改走 local_test 外部 ComfyUI 服务
后端 generate_hairline_redraw 跳过内置 Flux-2 重绘,改为产出 final(接缝融合基底)
+ 纯红遮罩 PNG(redraw_band_mask_base64,遮罩区=(255,0,0,255)、其余全透明)。

接口2 female(generate_grow_results_swap) 取 final+遮罩后在后端调 local_test
(0716add-hair.json 工作流) 完成重绘,结果作为生发图返回;male 分支不变。

测试页 test_interface12.html / test_interface12_final.html 改为两阶段:
先生成 final+纯红遮罩,再前端调 local_test 重绘并展示;color_match 默认不勾选。

local_test/app.py 加 CORS 头(OPTIONS 预检),支持浏览器跨域直连。
