Have you ever had a "painless migraine" - where your vision in both eyes slowly gets overtaken by a fuzzy c-shaped scintillating scotoma over the course of 30-60 minutes, but is *not* accompanied by pain?

Yes first time I had it they took me to a hospital poked and prodded for 3 days and discharged be with Coumadin (which made me sick). 2d time 10 years later I had it outside, came in an typed “visual migraine” into Google, bingo. Apparently my brain figured it out over the years

Yes, but pain does come later, typically 90 minutes or so
The scotoma is the warning sign to take painkillers

Yes - although only in one eye at a time, and for maybe 5-15 minutes. No pain, no discomfort, no redness - just a slow gray-out until all I could see was a tiny pinpoint. No C-shape, but definitely had the "lightning cloud" while it was coming or going.

twice per year perhaps. painless but annoying, basically makes you blind for any practical purpose

Working in IT did this to me hard... Mix screens with fluorescent lights for 10+ years and your eyes will do the weirdest things.
