/* ==========================================================================
   AI Humanizer — stylesheet

   Organised as: tokens, reset, primitives, layout, then components in the
   order they appear down the page.

   Two theme rules worth knowing before editing:
     - Every colour is defined on bare :root as a light value first. The dark
       overrides only redefine tokens, never add new ones, so a component
       written against the tokens works in both themes for free.
     - The dark palette is applied both by media query (system preference) and
       by [data-theme="dark"] (explicit toggle), which is why each block is
       duplicated. The :not() guard stops the media query from overriding an
       explicit light choice.
