/*
  kenleedev.com — one stylesheet, no build step, no dependencies.

  Deliberately plain CSS. This site's job is to load instantly, work everywhere,
  and be editable by hand in a year without remembering a toolchain. A framework
  would add a build step and buy nothing a portfolio page needs.

  Light and dark both come from the reader's OS setting. There is no theme
  toggle, because a toggle needs JavaScript and this page needs none.
