…lation The previous approach called stylesheet.source.clear() + reparse() + update() which destroyed widget DEFAULT_CSS rules, collapsing the UI to a flat colored screen with no sidebar, no welcome text, and lost status bar centering. Replace with direct inline style application: cycle() picks the next theme, then sets background/color on Screen, HeaderBar, SessionViewer, and StatusBar via their .styles property. This leaves the stylesheet and all widget DEFAULT_CSS completely untouched. Theme colors are defined as a THEME_COLORS dict in the theme manager alongside the existing .tcss files.
