Fix slow home/tool loads by self-hosting Bootstrap/fonts and deferring analytics.

Date: 2026-08-08 15:40 Summary: Fix slow home/tool loads by self-hosting Bootstrap/fonts and deferring analytics.

[question] http://localhost:8788/zh/tools/images-to-gif 还是很缓慢，解决这个问题，首页也很缓慢http://localhost:8788/zh/

[try to solve] Server HTML itself is fast (~10–20ms). Slowness came from first-paint-blocking third-party assets: cdnjs Bootstrap, fonts.googleapis, and Clarity/Baidu analytics timing out on local/restricted networks.

Fix:

scripts/copy-site-chrome-vendor.mjs copies Bootstrap 5.3.3 and Plus Jakarta Sans woff2 into /vendor/
layout.ts / layout.mjs use same-origin CSS/JS/fonts; Bootstrap loads with defer
Clarity/Baidu inject after load + requestIdleCallback
Sidebar/home secondary card icons use loading="lazy"; gifenc was already same-origin
build:site / start:dev --no-build run the vendor copy

Check: home/tool HTML no longer references cdnjs/fonts.googleapis; critical same-origin assets load in parallel ~16ms.
