/* ============================================================================
   Caerus Digital website, drawn in Apple's design language (live since 2026-10-04).

   One stylesheet for every page in Mockups/CompanyWebsite/. Apple Human Interface
   Guidelines foundations: SF Pro (system font) only, Regular to Bold weights,
   semantic label/background colors with light and dark values, one accent
   (system blue) for links and buttons, Liquid Glass only on the floating nav.
   Content is full-width bands with hairlines, never floating cards (Matt's
   standing "no cards" override). Light/dark follows the system setting.
