<ul><li>Added null-coalescing defaults at top of <code>platform/components/toolbar.php</code> for all variables sourced from module <code>pagedata.php</code> files: <code>$page_description</code>, <code>$page_title_1</code>, <code>$page_icon</code>, <code>$page_icon_color</code>, <code>$module_id</code>, <code>$page_id</code>, <code>$moduleType</code></li><li>These are injected via <code>extract($pagedata[$page])</code> in each module index.php — when a module does not define a key (e.g. no <code>page_description</code>), PHP threw an Undefined variable warning that rendered inline in the toolbar HTML</li><li>All variables now default safely: strings default to empty string, <code>$moduleType</code> defaults to <code>member</code></li></ul>
