Summary: Enhance the existing micro-animations demo to include the UI patterns required for Glass and Unified theme testing.

Description:
We need a robust UI environment before we can test new tokens. This issue focuses strictly on the structure and layout of the demo, ensuring we have the right "surface areas" to test styles.

Scope:

• Workspace: The new demo exists in a branch (off the existing animations demo in org?) so a react dev and core dev could both check out the branch and have it running locally during the hackathon.
  • ensure that a custom CSS file can be loaded into the demo (and that changes are successfully hot reloaded)
• Expansion: Add a Wizard (triggered via Modal) to test secondary background headers.
• Enhancement: Add a Drawer to the Table view with text content directly on the background.
• Assets: Swap existing icons for RH branded icons.

Definition of Done:

• Demo updated in a PR (so there is a PR preview link) in org repo based on spec above
• Demo is functional and ready for token integration (no new tokens or styles required yet).
