- 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
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.
