 * Shortcodes, mainly for the privacy policy page:
 *
 *   [plugin=cookie-consent]show=consent-id[/plugin]
 *       The visitor's current consent ID (+ date and a copy button), or a
 *       "no consent stored yet" notice - filled in by the init script in
 *       global/index.php, so it always shows this browser's own ID.
 *
 *   [plugin=cookie-consent]show=settings-link[/plugin]
 *       A link that opens the cookie settings dialog.
 *
 * Also usable from a theme template:
 *   {plugin name="cookie-consent"}show=consent-id{/plugin}
 *
 * Shortcodes instead of plain markup because WYSIWYG editors tend to drop
 * an empty <span data-cc-consent-id> or unknown data-* attributes on save.
 *
 * @var string $show from the shortcode's parameters (buffer_script())
