修：draw-ui / oil-motion 原被当子模块指针收录 ⇒ 改为正常文件入库（两份内容原先对别人是空的）

一、问题（本轮实测）
`draw-ui` 与 `oil-motion` 目录里**各自带一个内嵌 `.git`** ⇒ 上一次提交把它们记成了 **gitlink（子模块指针）**
⇒ 仓库里只存了一个不属于任何远端的 commit id，**别人克隆下来这两份是空的** ✗（`git status` 显示 ` m draw-ui` / ` m oil-motion` ＝ 子模块内容有改动）。

二、处置（可回退）
· 把两处的 `.git` **挪走**（⛔ 不是删除）⇒ `归档/内嵌git-20261008/{draw-ui,oil-motion}.git`；
· `git rm --cached` 掉那两个 gitlink，再 `git add` 两个目录 ⇒ **按正常文件入库**（内容才真的进仓库）。

三、副作用（如实记）
挪走 `.git` 后，这两个技能**不能再原地 `git pull` 取上游更新**（要更新得重新拉一份覆盖）；
如需恢复其本地仓库，把 `归档/内嵌git-20261008/` 里的 `.git` 挪回原处即可。

+Use case: illustration-story
+Asset type: transparent hero illustration for the Oil Motion GitHub README
+Input image: use oil-visual/assets/characters/oil-character-turnaround-v1.png as the exact identity reference for both recurring characters.
+
+Create one polished editorial manga scene that clearly communicates turning keyframes and AI video into interactive web motion. The glasses stick-figure protagonist operates a long horizontal film-strip workbench. On the left is one intact slim smartphone-like product as the approved start keyframe; across the middle are several continuous motion frames; on the right the same product is cleanly separated into an exploded view as the approved end keyframe. A large physical scroll/scrub wheel and a thin progress rail visibly control which film frame is active. The warm-yellow Border Collie sits beside the rail, watching the active frame with a gentle curious expression. Keep the characters secondary to the film strip and transformation evidence.
+
+Preserve the supplied person's round head, three-strand hair, thin round glasses with clearly visible solid-black pupils, small smile, loose white T-shirt, slender line limbs, and height-to-head ratio. Preserve the supplied dog's narrow white facial blaze, folded ears, gentle dark eyes, compact seated body, fluffy white chest, warm-yellow coat map, and full side-resting tail. Do not make the dog a round chibi puppy.
+
+Style: professional oil-visual manga/comic ink illustration; clean confident black outlines with varied line weight; restrained circular halftone screentone; 90% black, white and halftone gray; warm yellow only on the dog, scrubber knob and a few tiny star accents; muted blue only on a few product/frame surfaces. Flat 2D editorial illustration, not 3D.
+
+Composition: wide horizontal 3:2 scene, readable silhouette, three visual regions from start keyframe to motion frames to end keyframe. Keep generous clear padding around the entire scene for compositing.
+
+Background: genuine transparency with a preserved alpha channel. Every pixel outside the subject must be fully transparent. No green/magenta/grey/white backdrop, checkerboard, gradient, texture, noise, shadow, floor, horizon, reflection or lighting variation.
+
+No text, letters, numbers, logo, watermark, interface cards, dashboard, extra limbs, duplicated dog, missing pupils, motion blur, glossy rendering, photorealism or cast shadow. Keep every subject fully separated from all image borders.
