/* Palm Court: the menu shell (src/shell.js). A tab bar (top; bottom on a phone; a rail on a phone on its side), the Play
   page and the frame around the Store, Locker, Challenges, Leaderboard and Settings pages. Loud on purpose: angled
   panels, a colour for every tab, things that bounce. All motion is transform and opacity (the compositor's), nothing
   here blurs what is behind it (the 3D court keeps running behind the menu), and html.calm (Settings > Reduce motion)
   or the system's reduced-motion preference turns every bit of it off. */
