/**
 * Cite Plugin – Frontend Styles
 * Version: 2.9.4
 *
 * Design: Refined academic / editorial.
 *   – Left accent bar anchors the box with scholarly character.
 *   – Header has a soft tinted background distinct from the content area.
 *   – Copy button uses primary accent; export/toggle stay ghost.
 *   – Export dropdown gains file-ext badges and slide-in animation.
 *   – Copy notification slides up from the bottom edge (not centred overlay).
 *   – Dark mode: auto (prefers-color-scheme), forced via [data-theme="dark"],
 *     or forced light via [data-theme="light"] — matches the Color Scheme setting.
 *   – Wikipedia output retains monospace block treatment.
