2019 Lexus GS — a/C is cold on the highway but warm at stoplights — anyone dealt with this recently?

2019 Lexus GS 350, about 62,000 miles. The A/C works well with road speed but gets noticeably warmer at long lights, then cools again almost immediately once moving. Does that point more toward airflow/fan behavior than refrigerant level? I am in Charlotte.

I'd want a measurement, not a hunch. Move a coil or plug on the 2019 Lexus GS if it's cylinder-specific and see whether the code follows. Don't erase codes until someone who can help has seen them. Had a similar mess a couple years ago and that's what finally sorted it. This is the version I'd tell a friend.
