- README.md restored to Chinese (the default for Huasheng's primary audience)
- Added language toggle at top-left: English link in Chinese README, Chinese link in English README
- Added bilingual tagline in Chinese README hero
- Added demos/hero-animation-v9.mp4 (10MB) as hero animation, fallback to w3 GIF
- English README created as README.en.md with same demo gallery assets
Fixes: prior commit mistakenly replaced Chinese README entirely with English version
Based on real DJI Pocket 4 launch animation failure (2026-04-20):
- Add Principle #0: Fact Verification First (WebSearch before assumptions)
- Upgrade §1.a from 'Brand Asset Protocol' to 'Core Asset Protocol':
logo/product-shots/UI are now first-class assets, colors auxiliary
- Update workflow Step 1/2 to enforce the new order
- Add 'CSS silhouette for product shot' to anti-slop list
- Translate README.md to English (international audience)
Darwin score: 62.3 → 86.7 (+24.4)
The repo targets an international developer audience on GitHub,
so the README should be in English while SKILL.md (agent-facing)
stays in Chinese for Huasheng's workflow.
Also sync README to reflect the §1.a upgrade from 'Brand Asset Protocol'
to 'Core Asset Protocol' (logo/product-shots/UI are first-class assets,
colors become auxiliary). Added Fact Verification First (Principle #0)
to the Core Mechanics section.
