/* css/n64-props.css — the N64 layer
   Props are low-poly 3D objects drawn by js/n64-props.js into [data-prop]
   placeholders; the words beside them use the HUD voice: a chunky display
   face with a hard, unblurred drop shadow, the way a 1997 pause menu was
   lettered. Panels are flat and square-cornered with a double sand-gold
   frame — a dialog box, not a sheet of glass. */
