- gzip on(js/wasm/json/css,图片刻意不压):Web 版首包 12.5MB → ~4.4MB - /app/ 加 Cache-Control no-cache(etag 304 协商,产物无 hash 不做长缓存) - 新增 /shop/ location:与 shops API 同参数(jiu_shoplist 2r/s + UA 拦截 + limit_conn 10) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01JJ1g8XV1YhhmHRzhwWEW7o
