New CNCF project card? New cards go in kubestellar/console-marketplace, not this repo. PRs adding new cards here will be redirected.

Use a coding agent. This repo is primarily developed with Claude Code (Opus 4.5/4.6). It knows all codebase patterns (isDemoData, useCardLoadingState, locale strings, DCO). Manual PRs that miss required patterns will be sent back.

📝 Summary of Changes

Storybook had a major-version drift (8.6.18 vs available 10.4.6) flagged by Auto-QA. This update moves the Storybook toolchain to 10.4.6 and applies the required package-import migration to stay compatible with 9.x/10.x package consolidation.

• Dependency alignment
  • Bumped storybook to ^10.4.6
  • Bumped @storybook/react, @storybook/react-vite, and @storybook/addon-a11y to ^10.4.6
• 9.x/10.x migration compatibility
  • Replaced deprecated @storybook/test imports with storybook/test in story files
• Breaking-change audit (9.x + 10.x)
  • Verified current .storybook config is already ESM-compatible
  • No additional config/API refactor was required for this repo’s current Storybook usage

// before
import { fn } from '@storybook/test'

// after
import { fn } from 'storybook/test'

Changes Made

• Updated Storybook dependencies in web/package.json to ^10.4.6
• Refactored Story imports from @storybook/test to storybook/test
• Fixed version skew between storybook core and @storybook/* packages

Checklist

Please ensure the following before submitting your PR:

• I used a coding agent (Claude Code, Copilot, Gemini, or Codex) to generate/review this code
• I have reviewed the project's contribution guidelines
• New cards target console-marketplace, not this repo
• isDemoData is wired correctly (cards show Demo badge when using demo data)
• I have written unit tests for the changes (if applicable)

Screenshots or Logs (if applicable)

N/A (dependency and Storybook import-path update only).

👀 Reviewer Notes

• This PR intentionally avoids lockfile regeneration and local install; dependency resolution is deferred to CI as requested.
• If CI surfaces environment constraints for Storybook 10 (e.g., Node runtime floor), that should be handled in CI/runtime config, not in this dependency-only PR.

Original prompt

Fix issue #19161 by updating Storybook from version 8.6.18 to 10.4.6.

The Auto-QA security scanner has detected that Storybook has a major version update available (8.6.18 → 10.4.6).

Required changes:

1. Update web/package.json to change storybook from "^8.6.18" to "^10.4.6"
2. Update all @storybook/* dependencies to match version 10.4.6
3. Check for any breaking changes in the Storybook 9.x and 10.x migration guides
4. Update any imports or API usage if breaking changes exist
5. Do NOT run npm install locally - CI will handle that

Important notes:

• This is a major version update (8 → 10) so there may be breaking changes
• Review the Storybook changelog for versions 9.x and 10.x before updating
• If significant breaking changes require code refactoring, document them in the PR
• The PR must follow the commit convention: "[scanner] fix: update dependencies with available major version bumps" with DCO sign-off

The PR body should start with "Fixes #19161" on the first line to auto-close the issue when merged.
