Working from your answers: one shared household account · Organic design system · playful, quest-flavored copy · bottom nav = Home, Plan, Discover, Settings.
Accepted suggestions go to a Quest log (to-try pool). The AI builds each week from routine dinners + Quest log picks; you swap days, then it pushes to Google Calendar (app is source of truth). Shopping lists are grouped by dinner; uncheck what you already have. Each week's list becomes a post in the archive.
Assumptions to confirm: Shopping list and Quick dinners are reached from Home/Plan (not tabs) · Admin lives inside Settings · Photos are placeholders.
