/* ============================================================
   FEATHERWORK INVOICING — HOW IT WORKS PAGE
   Loaded alongside base.css + home.css: reuses the shared header,
   footer, .container, .btn, design tokens, and the .mock invoice
   component from those two files. Only adds what's unique here:
   the alternating step layout and the "send" mockup (a shape the
   homepage doesn't have).
