Thanks for being a calming voice here!
For what it's worth, I'm currently doing a heat test in nearly exactly the conditions my totes should be subjected to. I put some off-cuts and test pieces in my otherwise empty black tote and put it out in the Florida sun. Even in the fall, if it can survive the Florida sun, it can probably survive elsewhere. Not overly scientific by any means, but I'll post the results here in a bit. At least it can give some idea of what potential outcomes could be.
