The modifications affect both the sitemap index and urlset namespace definitions. No functional logic, control flow, or exported public declarations are altered.

75-75: LGTM — Namespace URIs align with official sitemap specification.

The official sitemaps.org protocol specifies http://www.sitemaps.org/schemas/sitemap/0.9 as the canonical namespace URI. All namespace declarations in the file (lines 75 and 127–132) correctly use HTTP URIs matching the specification. XML namespace URIs are identifiers and do not require URL resolution.

127-132: LGTM — All namespace URIs aligned with official specifications.

These namespace changes are correct:

• http://www.sitemaps.org/schemas/sitemap/0.9 — official sitemap protocol namespace
• http://www.w3.org/1999/xhtml — canonical W3C XHTML namespace
• Google extension namespaces (mobile, news, image, video) — use HTTP per Google's documentation

Pull request overview

This PR corrects the XML namespace declarations in sitemap files from HTTPS to HTTP, aligning them with the official sitemap protocol specification. XML namespaces are identifiers rather than URLs to be fetched, and the official specifications use HTTP.

Changes:

• Updated sitemap index namespace declaration from HTTPS to HTTP
• Updated all six urlset namespace declarations (main namespace plus xhtml, mobile, news, image, and video extensions) from HTTPS to HTTP
