Faithful Markdown rendering of game/rules.txt for the site: headings with
stable anchors, GFM tables and LaTeX formulas — the text itself is
unchanged (typos, the TODO/WTF notes, the broken (---ссылка---) marker and
the lore intro are all preserved as-is). The editorial pass (clarity,
nuances, organic cross-links, intro moved to the home page) follows in a
separate commit so its diff isolates exactly what changed relative to the
original. Registers the page in the RU sidebar.
