# Light Mode, Polished

## Frontend

A proper paper-white light theme that reads beautifully in bright rooms, plus a small personal touch: rename yourself in the user menu without touching your GitHub or Google account.

- Paper-white canvas with soft grid lines and theme-aware text across every panel
- Config forms, validators, inspectors, and the component palette all respect your theme
- Editable display name — click the pencil in the user menu to set a browser-local nickname
- Your custom name is scoped per account and never leaves your browser
- Colored buttons, status pills, and AWS service badges keep their contrast in both modes
