/* ==========================================================================
   LLMSCAPE design system.

   Same system as the FreeRouter marketing site — monochrome grayscale, sharp
   corners (border-radius: 0), flat 1px-bordered cards, Krona One display font
   over Instrument Sans body, light/dark via Bootstrap's data-bs-theme with a
   system default. The two sites should read as siblings.

   What differs, on purpose: the accent is cyan rather than FreeRouter's green,
   so a reader can tell them apart at a glance, and custom classes are prefixed
   `ls-` rather than `fr-`. Everything else is deliberately shared.

   This file is copied verbatim into www/ by the build. Edit it here.
