Few hours later, around bedtime, my wife says I should check the
toilet. Sure enough, the water in the bowl is blue.

Make sure float is set so the water stops below the overflow tube.
Water in that tube goes right around the flapper and into the bowl.
If it won't stop, you need a new float valve.
That's what I think, from my vague memories. Maybe.
