/*
 * styles.css
 *
 * Shared design system and layout styles for the QuranPath landing-page concepts.
 * Exists so all mockups and the final site reuse the same brand tokens, spacing,
 * and responsive patterns while only changing composition between concepts.
 *
 * Key things to know:
 * - Uses existing QuranPath colors and app assets rather than introducing a new brand
 * - Supports three concept modifiers: concept-a, concept-b, and concept-c
 * - Includes the final production-ready landing-page sections used by site/index.html
