/* djoubert.co.uk: one stylesheet, two skins.
   Light (the default) follows design A: teal banner, plain headings, pills.
   Dark follows design B: terminal prompts, amber tags.
   prefers-color-scheme picks the skin. There is no toggle: remembering a manual choice
   would need a script, and this site has none. Order matters: shared rules, then
   light-only, then dark-only, then the phone layout, then dark phone tweaks. */
