- Single source of truth for theme: theme.py tokens, FluentDialog base for all dialogs, setCustomStyleSheet migration, theme applied before window creation, SystemThemeListener for auto mode - Responsive layout: ScrollablePage base with as-needed horizontal scrolling, word wrap on dashboard labels, adaptive dashboard grid, realistic 860x560 window minimum - Real country flags (flagcdn PNG set) with themed border and fallback - Active server row marked by accent stripe only (no synthesized bold) - Subscription polish from parallel work (QR utils, http, diagnostics) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

"""Base dialog that participates in the qfluentwidgets theme mechanism.

|
Plain ``QDialog`` subclasses get the OS default backdrop, which breaks the
|
|
half-transparent fluent QSS in dark mode and leaves ``QPalette`` roles
|
|
(``PlaceholderText``/``Text``) out of sync with the theme. ``FluentDialog``
|
|
paints its surface from the :mod:`theme` tokens and re-applies everything on
|
|
``qconfig.themeChanged``.
