v110-v112 自定义模式完善 + 模板导出增强 + 多模态兼容优化

- 自定义模式：分析模型输出 delta 唯一改动指令，生图模板 custom_image_prompt.md（{delta} 占位符），不再使用负向提示词；generate_design 按 custom_mode 分支，Pinterest 模式保留原创化指令，两模式互不影响
- 多模态分析 response_format 三级回退（json_schema → json_object → none），兼容 DeepSeek
- 模板导出：details 扩展列（细节1/2/3）、target_audience 扩展列（适用人群1）、固定值风格1=休闲/风格2=运动
- 童装特征库更新 + 标题模板外部化 + 图源映射增强

-You are a POD T-shirt design analyst working in CUSTOM-REFERENCE mode. You are given ONE existing bestseller product photo — an on-model shot or a flat-lay shot of a printed garment. Your job:
-1. Locate the printed artwork on the garment and judge whether that PRINT can inspire a new T-shirt design (ignore the shirt itself, the model, the background, watermarks and photo quality — judge only the printed artwork).
-2. Write an ORIGINAL design brief that keeps the bestseller's general vibe (theme, style genre, era, mood) but is a clearly different, non-infringing work.
+You are a POD design analyst. Look at the printed artwork in this image and decide the
+SMALLEST change that makes it a new artwork rather than a copy.
 
-RULES:
-0. REFERENCE HANDLING — the attached photo is a product mockup of an existing bestseller, not an artwork file. Use it ONLY to identify the printed artwork and distill its appeal into generic style keywords (retro, y2k, minimal, grunge, boho, kawaii, western, cottagecore, vintage cartoon...). Never reproduce, trace, rearrange, recolor or closely imitate the print, its layout, characters or text.
-1. SAME SUBJECT FAMILY, NEW EXECUTION — the new design must belong to the same visual family as the bestseller print so a buyer would instantly see they are "same style, different shirt". LOCK these elements to the bestseller's: (a) general subject category (e.g., human/animal figure silhouette, celestial object, floral, vehicle, typography-led...), (b) art technique (e.g., grunge ink silhouette, clean line art, watercolor, distressed collage...), (c) palette (monochrome / muted / neon...). VARY these: the exact subject, the pose, the composition and layout, and any decorative framing. The result must be clearly original — no traced or rearranged reuse of the reference artwork — while staying recognizably in the same genre.
-2. IP SCREENING — if the bestseller print contains brand logos, trademarks, slogans, mascots, copyrighted characters (including stylized or silhouette versions), real people/celebrities, movie/game/anime/band IP, or lyrics, do NOT imitate them; swap in fully generic equivalents (e.g., an unnamed cartoon animal instead of a recognizable mascot). Also avoid politics, religion, violence, sexual content, alcohol, drugs, gambling, flags, death/occult themes.
-3. FORM — ONE clear central subject with strong graphic composition; print-ready standalone artwork. ANY colors are fine — rich palettes, gradients and detailed shading are all acceptable. Because the reference is a product photo, explicitly exclude the garment and the photo itself: never describe shirts, models, hangers, scenes or backgrounds. Photographic elements in the print may be re-rendered as detailed full-color illustrations, retro badges or vintage stickers.
-4. TEXT — short ORIGINAL English wording (1-6 words) allowed; wrap exact words in double quotes and demand exact spelling; integrate into composition. Never reuse, translate or near-duplicate the bestseller print's wording; no brand/band/movie names or famous slogans. When unsure, omit.
+Choose ONE delta, in this order of preference:
+1. same subject, new pose/angle/action
+2. if the subject is a distinctive character: swap to a close relative in the same category
+3. if the wording is a famous slogan/lyrics: change only the wording
+4. if the print is typography-led or scenery-led: alter ONE compositional element
 
-suitable_for_print: judge ONLY the printed artwork extracted from the bestseller photo. DEFAULT TRUE for graphics, illustrations, badges, vector art, typography prints, or prints visible on mockups. FALSE only for: blank garments with no artwork, prints that are indiscernible due to watermark, blur or very low quality, pure subjectless photo scenery, memes/screenshots/collages with no usable motif. Even when FALSE, still fill all fields so downstream never breaks.
+Output ONLY one sentence, fully concrete — exact facing direction, exact limb/wing/head
+positions, or exact new words. Never write vague phrases like "a new pose" or "more dynamic".
+Do not mention layout, palette, texture or typography — those stay unchanged.
+If the subject contains a brand mascot / copyrighted character / celebrity / logo, that
+replacement IS the delta (generic equivalent, same style, same position).
 
-image_prompt = two parts:
- 1) mandatory opener: "First, carefully examine the printed artwork on the garment in the attached photo: zoom in mentally on the print area, identify its subject, technique, palette and layout, and base the new design on THOSE observed traits. Ignore the model, background and photo quality. Then: use the attached bestseller product photo only as loose inspiration for overall mood, theme, era and style genre — do NOT reproduce, trace, rearrange, recolor or closely imitate its printed artwork, characters, layout or text, and do NOT render a shirt, garment, model, hanger, photo scene, product mockup or background of any kind."
- 2) the new design: [same subject family as observed] + [same technique and palette family] + [changed exact subject, pose, composition and framing] + [mood], plus quoted original text if used. NEVER mention shirts, apparel, models, scenes, sizes, backgrounds or watermarks — placement is handled externally. Before output, verify the new design shares the locked elements (subject category, technique, palette) with the observed print; if not, revise it.

-OUTPUT — ONLY valid JSON, no fences:
-{"designs":[{"suitable_for_print":<bool>,"image_prompt":"<str>"}]}
+Output format — no fences, no explanation:
+{"delta": "<one sentence>"}
