/**
     * SiteHeader — universal, prop-driven site header for hiai-ui
     *
     * Adapted from projects/webs/svelte-app/src/lib/components/SiteHeader.svelte.
     * Stripped of:
     *  - $app/state, $app/navigation, getContext('t'|'siteContent'), palettes,
     *    globalThemeState, nidoStructuredContentSeed (all webs-specific)
     *  - CrocoNav / HiaiLogo / Logo special-cases
     *  - Style selector (department dropdown, palette switcher)
     *  - Page-driven URL query rewriting (design / style / lang persistence)
     *
     * Replaced with a single `config` prop + three callbacks. Parent owns state.
     * Reuses hiai-ui's own LanguageSelector, ShareButton, and ThemeToggle so the
     * same picker UX is identical across consumers. ThemeToggle is only used as a
     * fallback when `onToggleDark` is not provided — controlled theme is preferred.
