36- English spelling conventions maintained throughout (colour, initialise, summarise)
37- Error handling improved with specific messages for common API failures (invalid key, rate limits, etc.)
38- Progress reporting unified through a `ProgressContext` interface for both TUI and CLI modes
39
40### Fixed
41
42- Initial API endpoint mismatch (using `/responses` instead of `/chat/completions`)
43- Nil pointer dereferences when handling optional feed metadata (author, dates)
44- String repetition syntax errors in Go (replaced `"="*80` with `strings.Repeat`)
45- CLI help/version flag handling to show information without requiring other arguments
46- Type compatibility issues with `openai-go` v3 API (message parameters, token usage fields)
