/* ============================================================================
   ShopLeads design system
   One stylesheet: tokens + typography + components. Import this and nothing else.

     <link rel="stylesheet" href="css/shopleads.css">

   Layout assumption: this file lives in a `css/` folder that sits next to a
   `fonts/` folder, so the @font-face url below resolves on any host:

     <root>/css/shopleads.css
     <root>/fonts/Geist-Variable-latin.woff2
     <root>/brand/logo-white.svg

   Surfaces: light by default, dark when the page sets `data-theme="dark"` on
   <html> (or when the OS asks for dark and the page has not forced light).
   Marketing / launch pages use the dark surfaces: <html lang="en" data-theme="dark">.
