/**
 * Galley Viewer Styles for MyTheme
 *
 * ROOT CAUSE: The default OJS theme includes viewPdf.less which styles
 * .galley_view, .header_view, #htmlContainer, #pdfCanvasContainer.
 * Since mytheme is standalone (no setParent), those styles are never loaded.
 * This file provides the missing styles plus sidebar layout.
 *
 * These pages are served by:
 *   - plugins/generic/htmlArticleGalley/templates/display.tpl
 *   - plugins/generic/pdfJsViewer/templates/display.tpl
