   ClinicOS — Chapter 07「啟程」

   Page-scoped under .st. Loaded after page.css, which still supplies the
   form components (.form, .field, .btn, .line) untouched — this file only
   changes the rhythm around them, never the controls themselves.

   The last chapter of a book, not a contact page. It opens on an empty
   room in daylight, looks back over the six chapters that came before,
   states the one thing worth keeping, and only then offers a way to
   begin. The form is the last step, not the first thing you meet.
