/* ==========================================================================
   style.css — 234 Guest in System 7 dress. 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 tablet).

   Theme: light = black on white, dark = inverted (white on black), like
   "Invert screen" on old Macs. Auto follows the system; the choice in the
   menu is stored. The paper itself (preview and print) is always white.
   Geist is only loaded for the canvas that draws the badge.
