Perf: Improve initial page load experience

[Fcmam5]

Describe the bug

As a user/crawler, I should see minimal content when pages are loading. And ideally, the page loads faster for me.

To Reproduce Steps to reproduce the behavior:

1. Empty cache and access to any page

Expected behavior

• See "something" while the page is loading.
• Load the main/important content at first, instead of none or everything

Screenshots

Google lighthouse score might also confirm this issue:

Possible solutions

• Prioritize content loading over unnecessary assets that can be lazy-loaded (for example article content over GH contributors)
• Dynamically render components
• Cache Backend-to-data source requests/queries
• Consider SSR
• Do more work on the backend (for example fetching contributors lists and returning their avatars).
