/**
 * A Sip of Living Waters - modern interface layer.
 *
 * Everything here is scoped to body[data-ui="modern"], so turning the flag off
 * in the Lab reveals the original v0.1.1 stylesheet underneath, unchanged and
 * complete. Nothing is duplicated: this layer only overrides.
 *
 * It is built entirely from the theme custom properties styles.css already
 * defines, so all 25 themes - including the five animated premium ones -
 * continue to work without any of them being edited.
 *
 * The design intent is a reading instrument, not an application: typography
 * carries the page, chrome recedes until touched, and motion is used only to
 * explain what moved where.
