   Redactory — shared chrome. Every page links this file; anything that only one
   page needs stays inline on that page.

   Black and white, plus the fixed semantic tokens (--hl, --ent-*, --ok, --av-*).
   Three theme states must all render: bare :root is light, the media query is the
   system default, and [data-theme] is the explicit choice. No colour is ever
   defined only inside a media or [data-theme] block.
