   LOZBI — AI SHOPPING ASSISTANT
   --------------------------------------------------------------------------
   A separate stylesheet on purpose: nothing in lozbi.css is touched, so the
   rest of the site cannot be affected by anything in here. Every class is
   prefixed ai* / aichat* so there are no collisions either.

   It borrows the site's own design tokens (--red, --ink, --line, --display…)
   which are already defined on :root by lozbi.css.
