Joycelyn 李子彤 Design Studio v3.9 — PHP 8.2 edition

Target environment:
- PHP 8.2
- WordPress 6.6 or newer
- Compatible target: WordPress 7.1.3

Changes/checks:
- Theme metadata updated for PHP 8.2 / WordPress 6.6+.
- Existing theme PHP files checked for common PHP 8 removed constructs (mysql_*, each(), create_function(), split/ereg, curly-brace offsets).
- Form POST handling modernized with wp_unslash() before sanitization.
- Existing local-avatar, social media, header/logo and site settings retained.
- Existing WordPress database settings are not reset when switching to this theme version.

Important:
This package updates the Joycelyn theme itself. Before changing the server from PHP 5.6 to PHP 8.2, WordPress core and every active third-party plugin must also be compatible with PHP 8.2.

Contact Email update: the field may be left blank. The old support@elockers.com.au default has been removed.

Blank Email fix: removed WordPress admin-email fallback from the settings field and front-end display. Empty Email now remains empty after saving; front-end Email row is hidden. Contact form may still use the WordPress admin email internally as a delivery fallback.
