Covers the user-visible surfaces that the main chat-UI test doesn't: 1. Compare tab (/chat?compare=...): assign two models, send 2 prompts, assert both panes respond. 2. Recipes editor (/data-recipes/$recipeId): click first template, verify the recipe-studio canvas mounts, open + close the Preview dialog. 3. Export route (/export): chat-only mode redirects to /chat; non-chat-only mode shows the export form fields. 4. Studio training route (/studio): chat-only mode redirects; non-chat-only verifies the tabs + sections exist. 5. Settings dialog tabs: Cmd/Ctrl-, opens the dialog; cycle through each tab and verify it isn't blank. The test assumes Studio is freshly booted (must_change_password=true) on BASE_URL with the bootstrap password in STUDIO_OLD_PW. It does its own change-password through the UI + model load via /api/inference/load, matching the pattern in playwright_chat_ui.py.
