/**
 * Themed visual divider line.
 *
 * @description
 * Renders a horizontal or vertical separator using the `bg-border` design token,
 * ensuring consistent appearance across light and dark modes.
 *
 * @ai-rules
 * 1. NEVER use a raw `<hr>` element — it lacks the required ARIA roles and design token styling.
 * 2. Use `orientation="vertical"` within flex containers to create vertical dividers.
