Comment (by westonruter):

 As I just [https://github.com/GoogleChromeLabs/wpp-
 research/pull/201#issuecomment-3447997500 commented] on the wpp-research
 PR, I just realized that I was testing without far-future expiry on the
 static assets. So the cached results were still involving conditional
 requests which returned `304 Not Modified`. I patched the wordpress-
 develop environment to ensure far-future expires were present:

 {{{#!diff
 diff --git a/tools/local-env/default.template b/tools/local-
 env/default.template

 +       }

         location ~ \.php$ {

                 fastcgi_split_path_info ^(.+\.php)(/.+)$;
 }}}

 And I re-ran the results. As seen in [attachment:"increasing-css-inline-
 size-limit.png"], the results are very similar.
