/* merlin public site theme. Hand-authored, served straight from priv/static
   -- no build step, no Tailwind. Adapted (and trimmed) from the itanimul.li
   design language: Literata prose, an OKLCH token system with color-mix
   shades, a tight justified reading column, and a JS-gated light/dark
   toggle. Deliberately its own stylesheet, unrelated to the admin panel. */
