1. Keep it Lightweight
Text-only pages like About should only weigh around 5KiB gzipped. Open your browser’s network tab and check for yourself!
Even though I expect most pages to be substatially heavier than 5KiB after adding images, , interactive elements, etc. the core HTML and CSS should remain about that size. Because that all fits in the TCP initial congestion window, the site will feel much more responsive.
