/**
 * MyApp theme - Bootstrap 5, dark sidebar / light content.
 * Loaded after Bootstrap 5's CSS and before page-specific plugin CSS.
 *
 * This file both (a) defines the app shell layout used by the rebuilt
 * chrome files (headbar.php, sidebar-shortcuts.php, navmenus.php,
 * navbar.php, footer.php, index.php) and (b) retints legacy class names
 * still emitted directly by system/tools.php, tools_controls.php and
 * tools_datatable.php (e.g. .infobox, .ace-icon) so those ~60 PHP
 * generator functions don't need to be rewritten to pick up the new look.
