  V1.2 — 2026-06-11
  Changes from V1.1:
  - Differentiated lastmod: foundational articles get earlier dates
    showing publication history, not bulk-publish signal
  - Differentiated changefreq per article type:
    - evolving standards (schema.org, ai.json, llms.txt) = weekly
    - active methodology articles = monthly
    - immutable/evergreen (bitcoin, opentimestamps) = yearly
  - AI technical articles raised to 0.8 (they explain your stack)
  - EU AI Act article raised to 0.9 + weekly
