viewer.js and viewer.css are built (src/build.mjs) from wmzy/sanguosha, https://github.com/wmzy/sanguosha, commit
8f4b693b654a6365d143a80003877219f6e08b22 (2026-09-28): its engine, replay player and the logic of its React table (its
hooks, prompts, action building and general selection), with this project's entry and table drawing, src/viewer/ (MIT, but for its stylesheet, below).

The drawing follows 无名杀 (noname), https://github.com/libnoname/noname, commit 90b58bb9934edb1712fd187a80c8323b7aeabaf3,
GPL-3.0: viewer.css reproduces the layout and woodden theme of its stylesheets (layout/mobile, layout/newlayout,
layout/default, theme/woodden, theme/style/hp), so treat it as covering GPL-3.0 material. The pictures and fonts it uses
are the art pack in art/, taken from 无名杀, with its own NOTICE (art/NOTICE): its 立绘 and card art are mostly the
commercial 三国杀 art of 游卡桌游, NOT CLEARED FOR PUBLICATION.
