* Fix SEO indexing: add hreflang, canonicals, sitemap per-locale entries Google Search Console showed 380 not-indexed vs 86 indexed pages. Root causes: missing hreflang tags on rendered pages (only in sitemap), no canonical on homepage, inconsistent canonicals wiping parent hreflang, sitemap only listing English URLs, trailing slash duplicates, and _next/static chunks being crawled as pages. Changes: - Add buildAlternates() utility for consistent canonical + hreflang - Add hreflang tags to all pages via alternates.languages in metadata - Add self-referencing canonical URLs to every page (homepage had none) - Expand sitemap to emit separate entries for each locale - Add missing /docs/custom-commands to sitemap - Remove skipTrailingSlashRedirect to normalize trailing slashes - Block /_next/ in robots.txt to stop chunk crawling * Add per-page alternates to docs sub-pages and blog index Docs sub-pages and blog index only returned title/description in generateMetadata, so they inherited the parent layout's alternates (pointing to /docs or /blog). Now each page sets its own buildAlternates() with the correct path so canonical and hreflang point to the actual page URL. * Derive openGraph.url from buildAlternates to avoid drift * Redirect non-English legal pages to English, remove from sitemap Legal pages (privacy policy, TOS, EULA) are untranslated English content. Serving them under every locale creates 54 duplicate URLs. Now: - Middleware 301-redirects /ja/privacy-policy etc. to /privacy-policy - Sitemap only includes English URLs for legal pages (no locale variants) - Legal page metadata uses static English-only canonical * Fix legal page redirect to only match /<locale>/<page> paths endsWith matched too broadly (e.g. /docs/eula). Now only redirects when the path after the first segment is an exact legal page match. * Skip next-intl for legal pages to prevent locale redirect loop Without this, a Japanese user hitting /privacy-policy could be redirected by next-intl to /ja/privacy-policy, which our middleware redirects back to /privacy-policy, creating a loop. * Rewrite legal pages to /en/ instead of NextResponse.next() Pages live under app/[locale]/, so skipping next-intl entirely would break route resolution. Rewrite to /en/privacy-policy etc. so Next.js can resolve the [locale] segment correctly. --------- Co-authored-by: Lawrence Chen <lawrencecchen@users.noreply.github.com>
