/* ==========================================================================
   style.css — 234 Doorbell in System 7 dress, the same skin as the guest
   portal: 1-bit, only "ink" and "paper", patterns of 2 px dots, Chicago-like
   type in window chrome and buttons, Geneva-like in body text. --px is "one
   classic pixel" (2 CSS px ≈ 72 dpi scaled to a phone).

   Theme: light = black on white, dark = inverted (white on black), like
   "Invert screen" on old Macs. Light is the default; "Auto" (follow the
   system) or "Dark" can be chosen in the menu and is stored per device.
   ========================================================================== */

/* Geneva is the face of this design. Apple's Geneva cannot be shipped, so devices without
   it (iPhone, Android, Windows) get Luxi Sans: drawn by Bigelow & Holmes, who also drew the
   TrueType Geneva, in the same Lucida style. A Mac never downloads it (Geneva comes first). */
