Comment (by westonruter):
As I just also [https://github.com/GoogleChromeLabs/wpp-
research/pull/201#issuecomment-3448044083 commented], I ran the benchmarks
for a broadband connection as well. See [attachment:"increasing-css-
inline-size-limit-broadband.png"].
👉🏻 For broadband as well as with Fast 4G, increasing the
`styles_inline_size_limit` results in a '''exponential decay''' in the
performance improvement for uncached visits whereas for cached visits
there is a '''linear''' performance degradation.
