ljg-card: 铸

内容进去，PNG 出来。模具决定形状。

参数

参数	模具	尺寸	说明
`-l`（默认）	长图	1080 x auto	单张阅读卡，内容自动撑高
`-i`	信息图	1080 x auto	布局跟着内容长，没有固定版式
`-m`	多卡	1080 x 1440	自动切成多张阅读卡片
`-v`	视觉笔记	1080 x auto	像杂志专题讲一个概念：问题→失败→转折→顿悟→命名
`-c`	漫画	1080 x auto	日式黑白漫画，按内容气质选漫画家
`-w`	白板	1080 x auto	和紙底手写推理链，箭头串概念

约束

输出是视觉文件（PNG），L0 里的 Org-mode、Denote、ASCII-only 规范不适用。

通用规矩

获取内容

URL：WebFetch 抓
粘贴文本：直接用
文件路径：Read 读

文件命名

从内容提取标题或核心思想作 {name}（中文直接用，去标点，≤ 20 字符）。

截图工具

node assets/capture.js <html> <png> <width> <height> [fullpage]

从 skill 根目录运行，依赖根目录 node_modules/ 里的 playwright。报错时：

npm install playwright && npx playwright install chromium

Footer

左侧：logo + 李继刚（模板已硬编码）
右侧：内容来源，可选。有明确来源（作者名、arxiv ID、网站名）就填 {{SOURCE_LINE}}：<span class="info-source">来源文字</span>；没有就留空字符串。适用于 -l、-i、-v、-c、-w（-m 多卡无 footer）。

交付

报告文件路径。

品味准则

不管走哪个模具，先 Read references/taste.md，全部模具共用的视觉底线：禁 Inter 字体、禁纯黑、禁三等分卡片、禁 AI 文案腔、禁假数据。

执行

按参数选模具，Read references/taste.md + 对应 mode 文件，照步骤走：

参数	mode 文件	模板
`-l`	`references/mode-long.md`	`assets/long_template.html`
`-i`	`references/mode-infograph.md`	`assets/infograph_template.html`
`-m`	`references/mode-poster.md`	`assets/poster_template.html`
`-v`	`references/mode-sketchnote.md`	`assets/sketchnote_template.html`
`-c`	`references/mode-comic.md`	`assets/comic_template.html`
`-w`	`references/mode-whiteboard.md`	`assets/whiteboard_template.html`
`-b`	`references/mode-big.md`	`assets/big_template.html`
