We need an Open Source alternative to AMP.

Fastest experience possible for SPA's (or pages) on both Mobile and Desktop.

• tcp segment size (MSS) default is 536B
• 1KB single ethernet packet
• 14KB single roundtrip (first frame is 1460B)
• 65kb upper bound for single frame

• Must fit in one request - TCP/HTTP connections are expensive (HTTP2 is not an option)
• Must support noscript users (Accesibility, TOR, etc.)
• Minimal time to first render
  • ...and second, and third
• No FOUC/FOUT (must use system fonts)

• Initial UI - the first thing a user sees, fits into first 500 bytes
• Full SPA UI - the fully functioning SPA, preferably fits into 14KB, or else 65KB

In the same page (in this order) (same TCP connection):

1. Load initial UI ( < 500 bytes)
2. Include noscript tag with redirect
3. Include a comment tag, containing the full SPA UI with all content and assets inlined
4. Include an inline script tag, which extracts the contents of the content tag and injects them into the page
5. done.

To assist in fitting initial UI into 500 bytes, convert CSS class styles into inline styles (in initial UI)
