Sunburnt micros- special care?

[Fishkeeper]

My dad got me some micro orchids for Xmas, and put them in front of a window for a few days until the 25th. Unfortunately, they were in front of a South-facing window, and they've gotten sunburnt. Most have at least 50% healthy foliage, but a nickel-sized S. fragrans only has two green leaf tips left.
Right now, I'm treating them more or less as normal. They're in the terrarium, kept lightly damp and humid, under indirect light suited to them. Aside from that, and removing any leaves that start to rot or go completely dead, do I need to do anything else?

They won't rot, so just leave them alone.

The burned tissue is dead, and will become dry and parchment-like, with no entry point for pathogens.

Good luck with your new orchids!
