你好！我准备使用 lemo-opuscar 制作短片。请先不要开始写剧本，帮我检查当前系统的制片底层依赖：
1. 检查 Node.js 版本是否达到 20+，并检查 Git 是否可用；
2. 检查 Python 版本是否达到 3.11+（或是否安装了 uv）；
3. 检查系统是否安装了 ffmpeg。
如果缺少任何工具，请给出适配我当前操作系统的安装命令和执行位置。安装完成后重新检查版本，全部通过后再告诉我可以开始。

Hi! I am preparing to produce a short film using lemo-opuscar. Before writing any script, please check my system dependencies for the media pipeline:
1. Verify Node.js is at version 20 or higher and Git is available;
2. Verify if Python is at version 3.11+ (or if uv is installed);
3. Verify if ffmpeg is installed and accessible.
If a dependency is missing, give installation commands for my operating system and say where to run them. Recheck the versions after installation and tell me to proceed only when all checks pass.

【完整画风原件】
仿威尔士画家 Kyffin Williams 的不透明水粉。方向性笔触宽为画幅宽 1/80–1/40，长是宽的 2–5 倍，边缘毛糙，完全覆盖；房子、墙、山脊用断续深色短线勾边；暗山上刮几笔亮绿或灰蓝。色板：天空和光淡金 #F1C565（别成芥末黄），田野绿 #86A03F，暗部煤黑 #1D1B1E，远山和水面灰蓝 #48505E，小点缀黄 #F6CF2F，其他颜色由这几色调出；故事围绕的那个主角用 #D97757，至少占画面高八分之一。田野和天空偏亮（约六成），山和房子偏暗。暖色调色不超过一成，暗角，颗粒。默认傍晚低角度侧光，田野受光，山脊有轮廓光。从高处真透视取景，一条路把视线引下去；小房子（或墙、石块）顺山坡一级级排开。动起来：烟或云循环飘动，横向跟拍。避免：水彩透明感、矢量平涂、发暗发脏。

【本文补充：先一帧请求】
请使用 lemo-opuscar 技能，在当前工作文件夹下建立 midnight-noodles 工程。采用上述《青山翠谷》的不透明水粉画风规则，先不要生成完整短片，用真实的前端绘图代码为我绘制一帧静态画面：
【题材场景】深夜雨后狭窄胡同里的小面馆。
【关键构图】老厨师老李（围裙使用主角专属色 #D97757，高度至少占画面 1/4）站在沸腾的面锅前，用竹筷挑起热气腾腾的细面；店内挂着一盏淡金暖灯（#F1C565），照亮升腾的蒸汽与粗木案板；窗外是深煤黑（#1D1B1E）的湿润石板路与灰蓝（#48505E）远墙。
【任务目标】请编写 index.html 渲染该静态帧，展示实际渲染出的图片绝对路径与源码位置，暂不制作整片。保持水粉的厚重刮刀色块与断续勾边，将光线合理转化为夜景光池，避免半透明水彩与塑料平涂。

[Complete Style Rules]
Opaque gouache after Welsh painter Kyffin Williams. Directional strokes 1/80-1/40 of frame width, 2-5 times as long, ragged, fully covering; broken dark dashes outline buildings, walls and ridges; dark hills flecked with lighter green or slate knife marks. Palette: sky and light pale gold #F1C565 (not mustard), fields green #86A03F, darks coal #1D1B1E, far hills and water slate #48505E, small accents yellow #F6CF2F, other colours mixed from these; the hero the story centres on #D97757, at least 1/8 of frame height. Fields and sky light (~60%), hills and buildings dark. Warm grade under 10%, vignette, grain. Default low late-afternoon side light: fields lit, ridges rim-lit. From high ground in true perspective, a path leading the eye down; small repeated buildings (or walls, rocks) stepping along slopes. Motion: looping smoke or cloud, a lateral track. Avoid: watercolour transparency, vector fills, mud.

[Single Frame Request]
Use the lemo-opuscar skill. Create the midnight-noodles project inside the current working folder and apply the Welsh Valley Gouache style above. Do not generate the full film yet; render a single static frame using real drawing code:
[Subject & Scene] A small noodle shop in a narrow alley on a wet night.
[Key Composition] The old chef Lao Li (wearing an apron in #D97757, occupying at least 1/4 of frame height) stands before a boiling pot lifting steaming noodles; a warm hanging lantern in pale gold (#F1C565) lights up the steam and wooden counter; outside are wet cobblestone streets in coal dark (#1D1B1E) and distant walls in slate blue (#48505E).
[Task] Write index.html to render this still. Report the absolute path of the rendered image and source code, without producing the full film yet. Maintain opaque gouache strokes and broken outlines, adapt lighting for a night scene, and avoid watercolor transparency or flat vector fills.

单帧画面的水粉笔触与用色非常满意！请以此画风为基础，规划 30 秒短片《深夜面馆》：
【故事弧线】
- 起（0–3 秒）：深夜小巷冷雨寂静，突然，面馆挑帘亮起一团淡金暖光（视觉钩子）。
- 承（3–18 秒）：老李熟练地揉面、滚水沸腾、挑起银丝细面，店内暖意渐浓。
- 转（18–24 秒）：一名疲惫的雨夜加班族推门而入，门上风铃脆响，带来一身风雨寒气。
- 合（24–30 秒）：老李端上一碗热汤面，年轻人低头喝汤露出释怀笑容；镜头慢慢拉出小店，暖光映亮湿润小巷。
【视听与导演要求】
1. 本例不需要旁白或对白，配乐采用民间拨弦乐器（物理建模），搭配环境雨声、沸水煮面拟音与风铃声；
2. 先为我生成包含 6–9 个关键镜头的故事板拼图（Storyboard）与 TREATMENT.md，汇报各镜头的景别与秒数规划；
3. 先停在这里等我确认故事板，不要直接开始全片渲染。

The gouache texture and palette in the static frame look great! Please proceed to plan the 30-second short film "Midnight Noodles" using this style:
[Story Arc]
- Hook (0–3s): A quiet alley in the night rain; suddenly, the noodle shop's warm lantern lights up.
- Setup (3–18s): Lao Li kneads dough, boils water, and lifts steaming noodles; warm atmosphere builds up.
- Turn (18–24s): A weary commuter pushes open the door; the wind chime rings against the cold rain outside.
- Resolution (24–30s): Lao Li serves a hot bowl of noodles; the customer smiles; camera slowly pulls back, framing the warm glow over the alley.
[Audio & Directing]
1. No narration or dialogue is needed for this example. Use folk plucked string instruments for the score with ambient rain, boiling water foley, and a wind chime;
2. Generate a contact sheet storyboard with 6–9 key frames and TREATMENT.md, showing shot types and duration breakdown;
3. Pause here and wait for my approval before full rendering.

故事板分镜与节奏确认无误，请正式启动全片合成：
1. 渲染输出标准 1920×1080、24 fps 的 30 秒 MP4 成片；
2. 完成配乐、拟音与多轨混音，将整片响度归一化至约 -14 LUFS；
3. 如有对白台词请同步导出对应时间轴的 .srt 字幕文件；
4. 交付物完整保留在当前工程目录下：MP4 成片、代表性高光海报 poster.jpg、TREATMENT.md、第三方素材声明 CREDITS、以及可以在本地重新执行构建的 build.sh；
5. 完成后请告诉我所有产出文件的具体绝对路径。

The storyboard and pacing are approved. Please proceed to full film rendering:
1. Render a 30-second MP4 at standard 1920×1080, 24 fps;
2. Complete score synthesis, foley, and multi-track mastering normalized to ~-14 LUFS;
3. Export an aligned .srt subtitle file if there are voice lines;
4. Deliver all assets inside the project folder: final MP4, highlight poster.jpg, TREATMENT.md, CREDITS, and a reproducible build.sh;
5. Report the exact absolute file paths once completed.

成片整体效果很好！请仅针对以下三处做局部代码微调，保持其他镜头与逻辑不变：
1. 【光影提亮】：第 6–10 秒老李下面镜头的店内主光偏暗，请将面锅上方的淡金光池（#F1C565）受光面亮度提高 15%，让水蒸气的高光轮廓更清晰。
2. 【动作停留】：第 20 秒推门进店的特写切换过快，请将该镜头延长 0.8 秒，给门上风铃摇晃一个清晰的视觉停顿，后续镜头时间点顺延。
3. 【音画对齐】：面碗落桌的撞击拟音比画面提前了约 6 帧（0.25 秒），请在统一时间轴 timeline.js 中将该音效事件后移 0.25 秒，精确对齐碗底接触木桌的瞬间。
修改后请执行 build.sh 重新生成成片，并给出新成片路径。

The overall film looks great! Please make targeted local adjustments to the code without altering other shots:
1. [Lighting]: The key light in the noodle cooking shot (6–10s) feels a bit dim. Increase the intensity of the pale-gold light pool (#F1C565) above the pot by 15% to enhance the rim light on the steam.
2. [Pacing]: The close-up shot of pushing open the door at 20s cuts too quickly. Extend this shot by 0.8s to give the swinging wind chime a clear visual pause, shifting subsequent cues accordingly.
3. [Audio Sync]: The foley for the bowl hitting the counter triggers about 6 frames (0.25s) too early. In timeline.js, delay this event by 0.25s to align exactly with the moment the bowl touches the wood.
After updating, execute build.sh to rebuild the film and report the new file path.

在执行制片构建时遇到了以下错误，请仔细阅读报错上下文，定位是依赖缺失、页面脚本错误还是 ffmpeg 参数问题，并直接修改源码修复它：

伦勃朗、卡拉瓦乔式明暗油画，只有一盏顶光。约七成画面是看得出形体的暖暗部，大多是赭褐 #24150B，近黑 #070403 只在最深的角落。琥珀 #8F5D2A 中间调约两成；朝上的面亮到 #E2B673。主角整个站在光池里，受光部分至少占画面高的四分之一；眉骨把眼睛压进阴影。一处饱和的红 #9C1A1A。暗部薄而平滑地罩染，亮部是带亮笔脊的厚涂，笔触约画面宽的 1/100；过渡柔和，不用刮擦线条。琥珀光油，重暗角，细画布纹（±3%）。背景可有一处暖色亮口（窗、门洞、发亮的天边）；画内的小灯只是一小团光，不算第二个主光。镜头慢拉、慢推。对标 Francis Ford Coppola《教父》（1972），摄影师 Gordon Willis。避免：提亮暗部、平光、人脸跳出来、暗到看不清。

Chiaroscuro oil painting after Rembrandt and Caravaggio, one overhead light. About 70% of the frame is readable warm dark, mostly umber #24150B, near-black #070403 only in the deepest corners. Amber #8F5D2A mid-tones about 20%; top planes reach #E2B673. The hero stands in the light pool, lit area at least 1/4 of frame height; brows shade the eyes. One red accent #9C1A1A. Darks thin smooth glazes; lights thick impasto, ridged strokes about 1/100 of frame width; modelling soft, never scratchy. Amber varnish, heavy vignette, canvas grain (±3%). A warm bright opening (window, doorway, horizon) may glow behind; a small lamp in frame is a small glow, not a second key. Camera: slow pull-backs and pushes. Reference: Francis Ford Coppola, *The Godfather* (1972), cinematographer Gordon Willis. Avoid: lifting the darks, flat light, faces popping out, frames too dark to read.

矢量建筑剖面轴测图，用低角度二等角视图：剖切面沿接近水平的 7° 轴正对观众，进深沿 42° 轴、按一半缩短；屋顶和近侧墙剖掉，露出房间。剖切穿过主体所在之处（房子、塔、船、山坡）。切面填涂黑：深色混凝土带骨料，土层画 45° 斜线夹小石块。任何缩放都是 1 像素深灰线。默认白天、淡色天空：混凝土 #b3ada2、橡木 #d6b58a、炭灰 #3e4146、松绿 #3f6b3e，白墙、绿草坪、半透明蓝水。房间配家具和简洁的小比例人。夜景或其他暗光只是变体：叠乘三到四成月光蓝，亮灯的房间涂回暖色。镜头沿剖面慢慢升降，框住两三个房间，跟主体走一条不断的路线，最后停在占画面约八成的整张图上。避免：30° 等轴测、粗卡通描边、楼层间切镜头、图太小。

Vector section axonometric, low dimetric view: the cut face lies along the near-flat 7° axis, facing us, depth along the 42° axis at half scale; roof and near walls cut away to show the rooms. Cut through the subject's place (a house, a tower, a ship, a hillside). Poché on cut faces: dark concrete with aggregate, earth hatched at 45° with stones. 1 px dark-grey lines at every zoom. Default daylight under a pale sky: concrete #b3ada2, oak #d6b58a, charcoal #3e4146, pine #3f6b3e, white walls, green lawn, translucent blue water. Furnished rooms, simple scale figures. Night or other low light is a variation: multiply 30–40% moonlit blue, lit rooms painted back warm. Crane slowly framing 2–3 rooms along one continuous path; end on the whole drawing at ~80% of the frame. Avoid: 30° isometric, thick outlines, cuts between levels, a small drawing.
