play with AMP and snowpack configs

AMP is disappointing at best. The time-to-interactive is nowhere near as fast, nor the bundle size as lightweight as a Svelte equivalent.
I managed to implement SSG with Snowpack + Rollup and reduce the bundle time by tens of seconds though. I need to see how it scales to hundreds of static webpages, but the developer experience is muuuuch nicer and the bundle config is 90% smaller.
