# Spec Delta: tools-app

## ADDED Requirements

### Requirement: Carbon Design System UI
The tools pages SHALL be built on the Carbon Design System: Carbon web
components (version-pinned via CDN) for buttons, notifications, toasts, tags,
progress and tiles; Carbon-styled native form controls; IBM Plex Sans
typography and Carbon color tokens for layout. Errors, confirmations and
successes SHALL surface as Carbon notifications rather than ad-hoc alert
dialogs.

#### Scenario: Pages render with Carbon components
- **WHEN** any tools page is opened
- **THEN** its interactive controls are Carbon components (or Carbon-styled
  native controls) and its notifications render as Carbon notifications
