   Built as a SIBLING of the Kedil Solutions parent site: same editorial base
   (near-black hero, warm off-white light sections, Fraunces display serif),
   extended with a restrained "AI-first" accent kit.

   Base tokens, type scale, buttons, section rhythm, header/footer and marquee
   are inherited from the parent design system (kedilsolutions.com), then
   extended below under "AI-FIRST ACCENT KIT".

   No build step, no deps.
