   SeenLabs Guides — light design system
   resources.seenlabs.com/guides/

   Token names and class names are kept byte-identical to the original dark
   display-setup page, so that page adopts this theme by swapping its <style>
   block for a link to this file — no markup rewrite.

   NOTE ON --accent-light: on a dark ground it meant "lighter than accent".
   Here it means the same thing it did functionally: the text-safe accent.
   On paper that is DARKER than --accent. Every place the old page used it
   (link text, .step-no, .legend b, .callout .tag, .path, .tree .dir) stays
   legible because of this inversion. Do not make it a pale blue.
