// already cover these URL spaces via splat/placeholder rules at the Cloudflare
// edge. We enumerate the finite shapes here to keep `pnpm dev` / `pnpm preview`
// from 404-ing, without bloating public/_redirects with duplicate static rules.
//
// Exported separately so the link checker can skip existence checks on these
// entries — their targets (search pages, paginated views) are not in the sitemap.
