docs: 重写介绍段 + 删重复 w3 GIF

- 介绍段换 MrBeast 视角：去专业术语 / 改「3-30 分钟」/ 品牌资产双路径 / 强调 README 动画都是 skill 自己做的（proof by execution）
- 删除 hero 下方重复出现的 w3-fallback-advisor GIF（无描述版），只保留 Demo Gallery 里那张

-Thirty seconds later, you have a slide deck, an iOS prototype, a motion-design sequence, or an infographic. Drop it in an issue, paste it into Keynote, ship it to Notion.
+3 to 30 minutes — you ship a **product launch animation**, a clickable App prototype, an editable PPT deck, a print-grade infographic.
 
-It doesn't look like AI made it. Twenty real design philosophies are distilled into the skill (Pentagram's information architecture, Field.io's motion poetics, Kenya Hara's eastern minimalism…). The agent grabs brand assets, builds a design spec, generates HTML, runs Playwright verification, then critiques itself against a 5-dimension rubric.
+Not "decent for AI" quality — it looks like a real design team made it. Give the skill your brand assets (logo, colors, UI screenshots) and it reads your brand's voice; give it nothing and the built-in 20 design vocabularies still keep you out of AI slop territory.
+
+**Every animation in this README was made by huashu-design itself.** No Figma, no After Effects — just a sentence + skill run. Next product launch needs a promo video? You can make it too.

-30 秒后，你手里有一份 PPT、一个 App 原型、一段时间轴动画、一张信息图——做出来的东西有 Pentagram 的信息建筑、Field.io 的运动诗学、Kenya Hara 的东方极简，不是又一次 AI slop。
+3 到 30 分钟，你能 ship 一段**产品发布动画**、一个能点击的 App 原型、一套能编辑的 PPT、一份印刷级的信息图。
 
-背后是 20 种真实设计语言被蒸馏进 skill：agent 抓品牌色、搭 design spec、生成 HTML、跑 Playwright 验证，最后自己评审打分。
+不是「AI 做的还行」那种水平——是看起来像大厂设计团队做的。给 skill 你的品牌资产（logo、色板、UI 截图），它会读懂你的品牌气质；什么都不给，内置的 20 种设计语汇也能兜底到不出 AI slop。
+
+**你看到这篇 README 里的每一个动画，都是 huashu-design 自己做的。** 不是 Figma，不是 AE，就是一句话 prompt + skill 跑通。下次产品发布要做宣传片？现在你也能做。
