Thank you, I'm currently browsing the care sheets.

She does have UT heat in her enclosure, the UT heat sandwhiched between tile and wood I mentioned above. So she has belly heat like you suggested.

From what I understand she's been in this thing for her entire life (ie several years) with no problems. Wouldn't moving her out of it now (after an entire rehome move) just stress her out more and make her want to eat even less?
