Metadata

• Export generateMetadata(requestInfo, props) from loader.ts to return a Metadata object.
• Framework auto-renders the meta tags — no <MetadataRenderer> in the view JSX.
• Hierarchy: global-loader.generateMetadata → view generateMetadata (view wins on conflicts).
• alternateLocales: Record<string, string> renders one <link rel="alternate" hreflang="..."> per entry (keys are BCP-47 tags or x-default) — for a multi-language site, compute this once in global-loader.generateMetadata from requestInfo.pathname so every view gets it automatically, instead of declaring it per view. See [[27-i18n]].
