/*
 * ATLET web app -- signed-out screens.

 * The split-screen layout, the fixed 220px photo band on a phone, the
 * absolutely-positioned brand mark and the position of "Coaching without
 * borders." are a design that was reviewed and signed off as it stands.
 * Change those only when asked to.
 *
 * Everything directional is written as start/end rather than left/right, so
 * the Persian and English versions are the same stylesheet rather than two.
