/* -----------------------------------------------------------------
   LLM4ABM — colour schemes

   Three bright, high-contrast palettes. Each pairs a vivid "title bar"
   colour (the header, hero and footer panels) with a very light,
   same-hue page background, plus a small set of accent colours for
   links, buttons, tags and marks — checked against WCAG AA (4.5:1)
   for their actual on-page use, not just at a glance.

   --title-ink is a separate token from --panel-ink: it colours only
   the "LLM4ABM" title (nav logo, hero heading, footer logo), so a
   theme can style its title distinctly without changing the contrast
   of ordinary panel text (nav links, footer copy). It defaults to
   --panel-ink and is only overridden where a theme asks for it.

   Switch schemes from the front end with the swatch row in the
   header; the choice is written to localStorage by theme-switcher.js.
