/* Amy — marketing site.
   Editorial/magazine direction: the twenty character portraits are the product,
   so the page is built like a feature spread — big wonky serif, paper grain,
   asymmetric grids, and photography that breaks the column.
   Tokens mirror ios/Amy/Core/DesignSystem/Theme.swift so the site and the app
   read as one thing. */
