- Startup/UI: open main window with background; run dependency check on-canvas; hide footer during scan; reveal Next after debounce; add 600ms refresh and 9s failsafe; fixed background image replacement without clearing content. - Canvas helpers: route all canvas calls via installer/screen.py; consistent status drawing. - Installer script externalization: per-dependency templates + validator; compose install_dependencies.sh. - Dependencies: add Ollama and template; install order: brew → ollama → k3d → kubectl → helm → krew → cmctl → plugins. - Cleanup: removed deprecated splash and unused code paths.
