/* WAD Commander handout: the placeholder website for wadcmd.com and a two-page
   A4 handout, laid out as the front and back of a 1990s PC game box.

   One unit drives the whole layout: 1rem is 1/100 of a box face's width.
   - Print: a face is an A4 page, 100rem × 141.43rem (1rem = 2.1mm).
   - Landscape screens: a 16:9 face, 100rem × 56.25rem, fitted to the viewport.
   - Tall portrait screens (tablets): the printed A4 face, fitted to the viewport.
   - Anything smaller (phones): the faces flow, as long as they need to be.
   The palette, the type (the app's CP437 font) and the title bar follow the
   app and the press page (apps/press). */
