Provides a Loader that dynamically selects a highlight QML component based on configuration (line, square, full, full with line). It binds opacity and color properties to the loaded item, and includes a blink timer for attention-demanding windows. This pattern isolates highlight logic and allows easy extension by adding new highlight QML files without modifying the core logic.

Serves as the delegate for each desktop/activity in the pager grid. It manages task count, hover state, highlight opacity, and loads the appropriate representation (Pill, Text, Icon) via a Loader. Integrates TaskManager's TasksModel to track windows per desktop and handle attention requests. This component encapsulates per-desktop state and rendering, making it reusable for any grid-based pager.

Implements a QAbstractListModel that abstracts either virtual desktops or activities as a list model. It manages WindowModel instances per desktop/activity, handles page switching via D-Bus, supports drag-and-drop of windows between pages, and exposes roles like TasksModel for QML consumption. This is a well-structured C++ model that decouples KDE's TaskManager API from the QML UI, enabling reuse in other Plasma widgets.

Contains utility functions for label generation (with support for Roman, Hindu-Arabic, Chinese numerals), highlight opacity calculation, representation source selection, and task count updates. The numeral mapping arrays and template replacement logic are self-contained and could be extracted for use in other projects requiring multi-script numbering or configurable label formatting.
