0.2.6-dev: the 19 local 玩法说明 pages get a lossless WebP copy in tools/local-extract (25.6 → 17.4 MB; lossy waits for the owner's comparison) and the guide preloads only the next page (host bandwidth layer 0.3); golden: unchanged

- **Fonts:** OTF/TTF files are converted to WOFF2 by a built-in encoder (`tools/assets/woff2.mjs`: Brotli with null transforms).
- Its output was verified lossless against Google's reference `woff2` decoder.
- `fonts.css` lists WOFF2 first and falls back to the original file.
- Images stay PNG. WebP conversion is not done: it would need a native dependency. The local-client board textures are the exception: `tools/local-extract/extract.py` (Python, where Pillow is already a dependency) writes WebP copies of the 12 textures the 3D board downloads (`WEBP`: colour maps lossy at quality 95 with the alpha and the RGB under transparent texels kept, normal and data maps lossless) and `data/local-assets.json` lists the copies; the PNGs stay beside them for `tools/crop-board-atlas.mjs`. `extract.py --webp` adds the copies to an existing extraction without the client.
