Learned from a Roman Komarov blog post (https://blog.kizu.dev/input-range-thumb/) that you can attach a `view-timeline` to a range inputs slider thumb! Whaaaat. (Chrome Canary w/ Experimental Web Features flag on).

Observation: Range Input’s Thumb and Emerging CSS

Today would be a quick “observation”, but a longer prelude. I did stumble upon what I’ll elaborate on today back in June, but for several reasons I did not share or write about this. Today, I saw Adam Argyle’s CodePen, and first forked it, using that technique, and now I’m writing about it as a way to share my observations more widely.
