/**
 * Wiki Theme — "Protocol Atelier"
 * Docsify overrides that make the wiki match the main site.
 *
 * Loaded AFTER the vendored Docsify vue.css (CDN), so every rule here
 * wins the cascade. All color/type comes from the shared design tokens
 * in theme-vars.css — nothing is hardcoded except the constant-dark code
 * panel's syntax colors (verified for contrast against --color-dark, which
 * stays dark in both schemes). Light + dark are handled automatically:
 * theme-vars.css redefines the tokens under prefers-color-scheme: dark.
 *
 * Fonts: system stacks via --font-body / --font-heading / --font-brand.
 * vue.css pulls Source Sans Pro + Roboto Mono from Google Fonts via a CSS
 * @import; those families are overridden everywhere below so the browser
 * never downloads the gstatic font binaries. (The googleapis @import fetch
 * itself lives inside vue.css and can't be cancelled from here — see the
 * note in the close-out; the CSP owner can drop those hosts safely.)
