   colinodell.com — "engineered" design system.

   Every colour token is a light-dark() pair and `color-scheme: dark light` on
   :root hands the choice to the reader's OS — no toggle, no second palette to
   keep in sync. A browser with no preference gets dark.

   Bootstrap is gone. Anything a legacy content body still needs from it is
   shimmed in site-additions.css — not here.
