Not sure if you saw in Discord @scanash00 but I'm finally able to dig into this. A few points:

• I think leaning into getting as much of Margin in SSR as possible will be really nice, there's a ton that isn't strictly interactive and should be fine to render as plain HTML.
• Thanks to Astro's island architecture, we have to explicitly opt into making client-side components actually interactive and ship their JS. What this means is that everything else is plain HTML and we can use React as our lingua franca between static and dynamic resources without the JS penalty.
• I want to give moving auth to Astro's server a try, mainly just because? We'll see if this bears any fruit.
• We should be able to abuse Astro's view transitions to get that juicy SSR speed without the downside of losing client state and full repaints. Need to play around with it first
