SEO Search Guardrails

These rules protect search discovery and must remain enforced by scripts/validate_seo.py in CI.

sitemap.xml and rss.xml are XML-only responses. They must not render the shared HTML layout.
sitemap.xml includes canonical, indexable URLs only. Redirect-only URLs and authenticated routes are excluded.
Blog URLs use the post's actual UpdatedAt value for lastmod; the homepage uses the most recent active FAQ, announcement, or displayed blog update.
Sitemap collection must page through every published blog post. Do not introduce a fixed total-content limit.
/rss.xml is the one canonical feed. /feed.xml permanently redirects to it.
robots.txt declares one canonical sitemap and never blocks XML resources.
Canonical URLs always use https://www.taxbaik.com and include the current indexable path. Paginated and category-filtered blog pages set an explicit canonical URL.
