/**
 * WD Author — frontend styles.
 *
 * Design goals:
 *  - Inherit every colour and font from the active theme — no hardcoded hex.
 *  - Purely typographic / spacing — no heavy card or box shadow.
 *  - A single thin bottom rule visually separates the box from the image below.
 *  - Starts at opacity:0; the wp_footer script fades it in once placed.
 *  - Expose CSS custom properties so a theme can override without !important.
