site/rules.md is a faithful English mirror of the authoritative Russian
site/ru/rules.md — the same section anchors (so the in-page cross-links
and the RU/EN structure line up), the same LaTeX formulas with English
labels, and the same tables and engine nuances. Rewrite the English home
intro to match the Russian one and link to the rules, and register Rules
in the English sidebar. Completes the bilingual rules.
The duplicate-then-disappearing formulas were a Vue hydration mismatch,
not a CSS problem. markdown-it-mathjax3 v5 pulls the `mathxyjax3` fork,
which emits each formula's CSS as an in-content `<style>` block scoped to
a per-container `#mjx-<id>` that the static build never sets. The orphaned
scoped CSS left the screen-reader MathML twin visible (the duplicate), and
the in-`<main>` `<style>` elements break VitePress/Vue hydration
("Hydration completed but contains mismatches"), which strips the SVG
glyph `<path>`s and blanks every formula after the page finishes loading.
Downgrade to markdown-it-mathjax3 ^4.3.2 — the mathjax-full-based version
VitePress officially supports. It uses `juice` to inline all CSS into the
element `style` attributes (no in-content `<style>`), so hydration is
clean (glyphs survive) and the MathML twin is hidden by its own inlined
style (no duplicate). This also drops the earlier custom.css workaround,
which only treated the symptom and itself blanked the formulas.
Verified with a headless Chromium render of the built /ru/rules: all 10
formulas keep their glyph paths after hydration, no console mismatch, no
duplicate copies.
markdown-it-mathjax3 renders each formula as a visible SVG plus a MathML
twin (<mjx-assistive-mml>) for screen readers, hidden via CSS scoped to a
per-container #mjx-<id> selector. In the static build the containers carry
no id, so that scoped rule matches nothing and the twin renders as a
second, oversized (theme-monospaced) copy of every formula, in every
browser. Add a global visually-hidden rule for mjx-assistive-mml in the
theme CSS: the twin stays in the DOM for assistive tech but is removed
from view and from layout.
Editorial pass over site/ru/rules.md (on top of the verbatim port):
- moved the lore intro to the RU home page, rewritten in a modern voice;
- fixed typos, replaced the TODO/WTF cargo-tech note and the abandoned
(---ссылка---) marker with the verified mechanic and a real cross-link,
dropped the report TODO row;
- wove organic intra-page cross-links (#combat, #movement, #victory, ...);
- documented engine nuances verified against the code: ore auto-farming
and the capital / "запасы промышленности" store (industry capped at
population); cargo lost with ships destroyed in battle; and that a
losing race's colonists at a neutral planet are NOT lost — they stay
aboard (this corrects the audit note, verified in route.go).
Migration: delete game/rules.txt (its content now lives, authoritative,
in site/ru/rules.md) and repoint every reference to it (ui/frontend code
comments + tests, ui/docs, tools, ui/PLAN.md links). Record the
RU-authoritative rule in site/README.md and CLAUDE.md. The English
site/rules.md mirror follows in a separate stage.
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.
