[perf] Fix the loading times of the landing page

[JayanAXHF]

Current Statistics from Lighthouse:

[dated] 6th February 2026

1. FCP: ~4s
2. LCP: ~8s

Proposed fixes

• use an image delivery service and upload the gifs, etc. to it, rather than linking directly from third party websites
• use cloudflare caches
• lazy loading, only load when scroll to etc
• Use Astro's <Image/> tag to automatically optimise and convert images

Implementation Progress:

I would like to take a dig at this after #1028 has been merged. I noticed a couple of issues while building the site:

1. Layout shift when switching between light and dark mode
2. High memory usage

Hey @alabhyajindal, nice! I just left a comment there to speed things up

#1028 is no longer a blocker, we're not moving forward with it due to cross-platform rendering issues with the WASM demo. The usable changes have been extracted into #1071.

I think a good first step in reducing the sheer amount of data that we send it to use webp/avif files instead of .gif and other image files. iirc vhs can export directly to these file formats
