Why plain HTML archives well
Simple files are easier to move, diff, and restore than generated bundles.
Plain HTML keeps content legible even when the original tooling is gone. That matters more than clever build steps for tiny reference sites.
When pages are hand-sized, a backup can be inspected with standard tools and restored without rebuilding anything.
The tradeoff is repetition, but repetition is acceptable when the site is intentionally small.
