/**
 * Frontend styles for column AI Studio shortcodes / blocks.
 *
 * Loaded on the frontend (single column page) via wp_enqueue_scripts.
 * Covers:
 *   - .callout / .callout-* (owl character speech bubble)
 *   - <table> inside .column-detail-body (article tables)
 *   - <mark> highlight inside article body
 *   - .cas-related-card ("あわせて読みたい" link card)
 *
 * Per-character color: render_callback puts inline `style="color:<hex>"` on
 * the outer .callout, so currentColor cascades down to icon border, arrow,
 * label background. --callout-icon-image is set per-instance on .callout-icon
 * to the character image URL.
