/* The landing page. Everything else in the app is a round in progress and
   keeps still; this is the one screen whose job is to look like a game before
   anybody has played one, so it is allowed to bounce.

   Layered on style.css, which owns the shared dressing — the wordmark, the
   chunky buttons, the drifting dots and the reduced-motion switch. This file
   is only what is particular to the landing page: its layout, the demo and
   the two cards. */

/* --------------------------------------------------------------- layout */

/* A phone gets one column in reading order: the name, the buttons, then the
   demo, because the buttons are what somebody holding a phone came for. A
   desktop gets the name and the demo on the left and the buttons beside them,
   and the whole thing stops growing at a width a person can take in at once —
   the old page stretched every card to the edges of a 27-inch monitor. */
