/* Odysseus — the language switcher.
 *
 * Its own file because it is the ONE component that appears on both kinds of
 * page this site has: the assembled pages, which load /css/shared.css, and the
 * whole pages (home, changelog, security), which carry their own design tokens
 * in an inline <style> and load no shared stylesheet at all. Putting these
 * rules in shared.css would have styled half the site; copying them into three
 * inline <style> blocks would have been three copies to drift apart.
 *
 * Every value is a token with a literal fallback, so the file is correct in
 * both hosts: the tokens resolve on pages that define them, and the fallbacks
 * carry the pages that do not.
 *
 * No JavaScript is involved anywhere below. The menu variant is a <details>
 * element, which opens on click and on Enter/Space in every browser with
 * scripting switched off. That is deliberate: this control exists for readers
 * on networks where the reason the fonts are self-hosted is that Google's hosts
 * do not answer, and a switcher that needs a script to navigate is a switcher
 * that fails for exactly them.
