/*!
 * Gradient Fallback Featured Image — front-end banner styles.
 * Every visual value (gradient/height/radius/opacity/color/alignment/font)
 * is injected per-banner as a CSS custom property via the inline style
 * attribute — this file only defines how those variables are used.
 *
 * Every selector below is scoped under .gffi-banner (2 classes deep) rather
 * than flat single-class rules, so this survives being dropped into any
 * theme's own content-area typography (e.g. a common `.entry-content h2 {…}`
 * rule has higher specificity than a bare `.gffi-banner-title {…}` would).
