[hl7258888-commits]

Summary

Adds web clipper templates for 5 major Chinese content platforms — the first Chinese-language platform templates in this repo.

Template	Platform	Key Feature
WeChat Article	mp.weixin.qq.com	#js_content selector for clean article extraction
Zhihu	zhihu.com (Q&A + columns)	.RichText selector filters out votes, comments, recommendations
Xiaohongshu / RedNote	xiaohongshu.com	Carousel image dedup: :not(.swiper-slide-duplicate) + unique filter
Bilibili	bilibili.com	Auto-extracts BV number from URL for iframe embed; strips _哔哩哔哩_bilibili title suffix
Chinese News & Tech	WSJ CN, Caixin, SSPAI, 36Kr, Huxiu, V2EX, Jike, etc.	Multi-site catch-all for Chinese tech/news articles

Technical highlights

• Xiaohongshu image deduplication: XHS uses Swiper.js carousel that duplicates slides for infinite loop. The template uses CSS pseudo-class `:not(.swiper-slide-duplicate)` combined with the `unique` filter and a `join` trick to produce clean, deduplicated image embeds.
• Bilibili BV extraction: Chained filters extract the BV number from any Bilibili URL format for iframe embedding.
• WeChat `#js_content`: Targets the exact content container, avoiding recommended articles and UI chrome.
• Zhihu `.RichText`: Grabs only the answer/article body, skipping vote counts, comment sections, and sidebar content.

Test plan

• Tested on WeChat articles (mp.weixin.qq.com)
• Tested on Zhihu answers and columns (zhihu.com)
• Tested on Xiaohongshu notes with single and multiple images
• Tested on Bilibili video pages (BV number extraction + iframe)
• Tested on 36Kr, SSPAI, V2EX articles
