Built to finish the task, not trap your attention.

The interactive logic is isolated from the static page shell. Useful content arrives first, then only the tool interface that needs JavaScript becomes interactive.

  • No sign-up wall for core tools.
  • Responsive controls sized for touch and keyboard input.
  • Errors and results stay close to the action that produced them.
Accessible interaction

Focus states, semantic labels, reduced-motion support and responsive layouts are part of the base interface rather than optional polish.
