Pages to check:

• index https://aavalam.org/~kellyky/index.html
• today i learned https://aavalam.org/~kellyky/today_i_learned.html
• other pages, if created

Note: an issue #2 is already created for notes, the worst offender.

What 'done' looks like:

• Issue(s) should be created for offenses.
• Offending pages should be specified. Issues should be described specifically with clear actions needed.

Whether one issue / offense is created or one issue / page should depend on what is discovered and what logically makes sense. The point is that those issues should be actionable.
