How to treat black rot on cattleya?

Today I learned Sunset Valley orchid have seedling moss plug.
I woke up finding my cattleya with leaf rot from the rain couple days ago. The roots looks mostly fine so far, but this is my first time encountering this kind of problem. What should I do?

On second thought judging from the black mark pattern Im not even sure if this is a rot or a burn

That's sunburn. The roots and the rest of the plant look good. Just leave it alone; the sunburn will dry and the plant should be fine.
