/* livingbrain.wiki: the whole design system, ported from the Claude Design
   file `Living Brain.dc.html`. Tokens first. The inline script in <head> sets
   <html data-theme> from the stored choice, else the system preference; with
   no script the system preference decides (the media query below), dark by
   default.

   The accent is reserved for alive moments: pulses, new links, the live node,
   the primary action. Entity colours (--t-*) only label graph nodes.
   Light-theme --ink3, --accent and the entity inks are a little darker than
   the design file so small text clears WCAG AA (see COPY.md, Port notes). */
