View > Theme offers Follow system / Light / Dark, stored in the settings. Follow system uses the desktop's colour scheme where Qt reports it (6.5+) and is light otherwise. The dark theme is a deep indigo (#1A1D3A panels, #12142B entry fields and charts). The palettes live in the new ViewerTheme module. A switch applies at once: the application stylesheet is set again after the palette so every widget is re-polished (with a stylesheet active, polished widgets otherwise keep their old palette); widgets that bake colours into stylesheets use SetThemedStyleSheet, which re-applies them on ThemeNotifier::changed; toolbar icons draw their glyph at paint time through an icon engine, so the ink follows the theme (and stays sharp at any size); charts re-theme and rebuild. Hard-coded white backgrounds on entry fields and tables are removed in favour of the palette's base colour. The idle detector-status badge in the status bar is now transparent instead of an empty default-styled progress bar. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
