There's gotta be lots of duplicated styles. I've mostly been starting fresh with each page and copying similar bits around.

I've been a fan of htmx for a few years. I was already subscribed to the approach having previously cobbled stuff together which resembled hx-boost and hx-swap-oob. htmx feels natural to me, I feel I get to focus on what I want to accomplish vs thinking about how to use htmx.
