   Lahza — shared site chrome: tokens, nav, buttons, sections, footer, and the
   content components the inner pages are built from.

   Two brand rules carry most of the look: mint is never text on a light surface,
   and the gradient belongs to the mark alone — so every surface here is flat and
   structure is carried by green, never grey.
