+- **Page template loading lock** - Block ALL shortcode rendering during page template loading
+  - Added `$loading_page_template` flag in TemplateLoader
+  - template-wrapper.php now sets this flag before loading theme header/footer
+  - Shortcodes::render_template() checks this flag and returns early if set
+  - This prevents any recursion triggered by theme components, widgets, or other plugins during page template loading
+  - Main template rendering still works (uses Plugin::render() directly, not through Shortcodes)
