Allow users to read the AI analysis of past days, so they can get context on why the trend chart was so high/low. This kind of happens when you use the Time Travel feature on desktop, but it's a bit bugged, as sometimes the index number doesn't update and the chart usually stays in the same place.
The user should be able to select a past date in the World Tension page so they can read the AI analysis for that date and get better context about the tension trend chart. Maybe also add an indicator on the chart showing your current position.
