  Use when working with Bubble Tea (charmbracelet/bubbletea) — the Elm Architecture TUI
  framework for Go. Covers the Model/Update/View cycle, commands, messages, the View struct,
  renderer, input handling, program lifecycle, testing, component composition, integration
  with the Charm ecosystem (lipgloss, bubbles, huh, glamour), and production design patterns.
