/**
* renderLegalHtml renders a bilingual (RU + EN) legal document as a standalone, self-contained HTML
* page with a header language + theme switcher, mirroring the landing: a 🌐 language toggle and a
* ☼/☾ theme toggle, no "back". Both language bodies are rendered into the page; a small inline
* ES5 script toggles between them client-side (no reload), defaults to Russian (never the browser
* language, like the landing) and persists the choice, and applies the theme (system default plus a
* persisted manual override). On the offer page (`bodyClass === 'offer'`) it also transliterates the
* Cyrillic left in the EN body — the live price list is spliced in Russian, so the product names are
* transliterated for the English view. It backs every public legal page — the offer at `/offer/`, the
* privacy policy at `/privacy/`, the EULA at `/eula/` — served by the render sidecar.
*
* The markdown is trusted repository content plus the backend's own catalog projection, not user
* input, so the rendered HTML is deliberately not sanitised. The page carries its own minimal styling
* and script, so it needs neither the app bundle nor `app.css`.
