harden

Systematically strengthen interfaces against text overflow, internationalization, errors, and real-world edge cases.

- Covers text handling (truncation, wrapping, responsive sizing), RTL/CJK support, date/number formatting, and translation expansion planning

- Provides error recovery patterns for network failures, API status codes, validation errors, and permission states

- Includes edge case strategies: empty states, loading states, large datasets, concurrent operations, and boundary conditions

- Offers testing approaches: extreme inputs, offline scenarios, keyboard/screen reader validation, and performance under slow connections

Strengthen interfaces against edge cases, errors, internationalization issues, and real-world usage scenarios that break idealized designs.

Assess Hardening Needs

Identify weaknesses and edge cases:

- Test with extreme inputs:

- Very long text (names, descriptions, titles)

- Very short text (empty, single character)

- Special characters (emoji, RTL text, accents)

- Large numbers (millions, billions)

- Many items (1000+ list items, 50+ options)

- No data (empty states)
