- 后端 enrichment.ARTICLE_BODY_FONT_SIZE: 17 → 19(新写库的 LLM 排版版)
- 前端 style.css .article-body / .diary-para: 17 → 19,line-height 1.7 → 1.75
- 768px 媒体查询: 16 → 18,line-height 1.8 → 1.85
- 480px 媒体查询: 15.5 → 17

老文章也立即变大(前端 .article-body 兜底);新排版文章用新 inline style。
后端要等下一次 enrich 才落新行(原 inline style 还是 17px),
如果想老排版版立即也变,在 /admin/llm 手动 trigger 几篇 enrich 即可。
