Moe is the neotenous anime style that has become ubiquitous since the 2000s. Back in the day some anime actually had more than three ages.

I think it's in the ending montage, IIRC her scene is a few seconds of like "41st birthday stream" or something like that, indicating her character growth was just continuing to be more open and less obsessed with trying to be like a teen idol/influencer.
Edit: I found the scene, and it's actually her announcing that she just turned 42, and that's taking place within a year of the "admission" that she was 31.
Thanks for checking!
