File	Problem	Solution	Deps
`1-raw.ts`	`data.toString()` can't decode escape sequences — arrow keys produce mojibake	`createInput()` decodes raw bytes into structured events	`@bomb.sh/tty`
`2-parser.ts`	Duplicated event handling in data handler and flush timeout	Extract `processEvent()` as a pure function	—
`3-signals.ts`	Manual `render()` calls become difficult manage with scale. Use a library which can subscribe to changes and trigger a render after every state change.	`signal()` + `effect()` auto-renders on state change	`alien-signals` (choice optional, user can choose)
`4-modes.ts`	Change `seeings()` which requires a revert on before process exits.	`alternateBuffer()` + `settings()` — quit becomes a state flag	`@bomb.sh/tty`
`5-stream.ts`	Refactor overloaded data handler with an async iterator and flush all events in one callback.	Async iterator moves flush logic into its own function	`@bomb.sh/tty`
`6-events.ts`	One all event types including mouse movements and element transitions	Same iterator yields all types; reactive signals drive color transitions	`@bomb.sh/tty`
`7-focus.ts`	Double our inputs and handle focus changes (Tab) between them while still supporting transitions	Two panels, Tab/Shift+Tab focus, full reactive treatment on focused panel	`@clack/ui`
