/*
 * Life Adve — For 0-2 Years Program: interactive tutorial page styling.
 * Developed and maintained by QD World.
 *
 * Scoped entirely under the "z2y-" prefix so nothing here can leak
 * into or collide with the shared site stylesheet (css/style.css) or
 * any other page. Reuses the site's own brand tokens (--theme-color1
 * the lime green, --theme-color2 the deep teal, --title-font /
 * --text-font) so the page reads as part of Life Adve rather than a
 * bolted-on module.
