- 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 scrollable page (AC7).

|
``ScrollablePage`` is the common base for content pages: a vertical
|
|
``SmoothScrollArea`` whose horizontal scrollbar policy is ``ScrollBarAsNeeded``
|
|
(content wider than the viewport scrolls instead of being clipped), fully
|
|
transparent surfaces so the Windows 11 Mica effect shows through, and a
|
|
``body`` container with the standard page paddings.
|
|
|
|
Subclasses add their content to ``self.body_layout`` (children parented to
|
|
``self.body``).
