/**
 * Organic Growth - app shell layout.
 *
 * The member area sits inside the site's own theme, between its header and
 * footer. The theme keeps your branding and navigation; everything between is
 * ours.
 *
 * ON MOBILE the left rail becomes a bottom bar. That is not decoration: most of
 * this platform's members are on Android phones held in one hand, and the
 * bottom of the screen is the only area a thumb reaches comfortably. A hamburger
 * menu at the top would put every primary action out of reach.
