Detailed Description

class guitar_prometheus::Theming::ThemeManager;

The manager is constructed once at app launch (in main.cpp), holds the single [AppLookAndFeel](/api-reference/classes/classguitar__prometheus_1_1theming_1_1applookandfeel/) instance for the process lifetime, and registers it as the default look-and-feel on juce::Desktop. UI panels read [currentPairId()](/api-reference/classes/classguitar__prometheus_1_1theming_1_1thememanager/#function-currentpairid) / [currentMode()](/api-reference/classes/classguitar__prometheus_1_1theming_1_1thememanager/#function-currentmode) for menu check-mark state and call setPair(...) / setMode(...) to cause a theme swap.

Inherits juce::ChangeBroadcaster so the menu can refresh its tick state when a theme swap happens outside the menu’s own command path (e.g. an OS dark-mode toggle while Follow System is active).
