 * Pizarra digital mode - see shared/pizarra.js. Every rule is scoped to
 * html.is-pizarra, which only that script sets, so loading this file costs
 * a normal visitor nothing.
 *
 * The body is laid out at the virtual size (--pz-w x --pz-h) and scaled by
 * --pz-scale to fill the screen. vw/vh units still measure the REAL screen,
 * so any rule sized with them that matters in a game gets a --pz-vw/--pz-vh
 * version here (or in that game's style.css).
