- WelcomeScreen: a greeting for the hour over the owner's composer,
starters and cards, centered while it fits and scrolled from its top
when it does not
- SuggestionChips, FollowUpSuggestions and CapabilityCards: each press asks
the owner; rows and cards are Tab stops
- PromptLibrary is documents::TemplatePicker over saved prompts
- gallery: starters and cards fill the welcome composer, a saved prompt
fills it too, send clears it with a toast, a follow-up asks its question
