Keep page text shippable

Avoid strong profanity in rendered text, seeds, and SQL literals.

Write clean page text

1. Keep strong profanity out of page text, seed data, and SQL string literals.
2. Remember the pre-live gate reads rendered text plus string literals.
3. Fix flagged lines and commit again after a block.
4. Expect a blocked deploy to keep serving the previous version.
