How these pages are built

Nothing here needs a script to be read. They are ordinary HTML and CSS - ordered headings, alternative text on images, and touch targets sized for a phone.

What this does not say

Technical subjects are written as plainly as the subject permits. That is a limit of the subject, not a design choice.

If this changes

The wording here may change. Whatever is published on this page is the version in force.
