  1. Pick one convention per layer: snake_case for Python/DB columns, camelCase for JSON/JS, kebab-case for URLs and CSS classes. Convert at the boundary, not everywhere.
  2. Slugs should be lowercase ASCII, words joined by -. Strip accents first (Unicode NFD normalize, drop combining marks) so "Café" becomes "cafe", not "caf".
  3. Collapse runs of separators: "a -- b" should give a-b, not a-----b.
  4. Watch acronyms: parseHTTPResponse splits into parse/HTTP/Response; naive regexes yield parse_h_t_t_p_response. Split on lowercase-to-uppercase and on UPPER followed by Upper+lower.
  5. Never use slugs as unique IDs without a uniqueness suffix; two titles can slug identically.
  6. Keep slugs stable after publish. Changing them breaks links; add a redirect if you must.
