/*
 * The Way of It
 * A design inspired by the meeting of Zen and The Work
 *
 * Design principles:
 * - Emptiness as presence (negative space)
 * - Simplicity revealing depth
 * - The quality of inquiry - openness, questioning
 * - Breath-like rhythm in layout
 * - Enso (Zen circle) as subtle motif
