nextjs-firebase-slice

name	nextjs-firebase-slice
description	Implement or refine a MoneyPulse Web frontend slice that reads de-identified Firebase data using Next.js, React 19, and the repository's data-boundary rules.

When using this skill:

• verify the owning phase spec first
• identify the page, hook, component, and Firebase data contract involved
• keep projected data read-only unless the spec explicitly defines a cloud-only overlay write
• add clear loading, empty, error, and freshness states
• validate with the smallest relevant build or test command

If the slice changes contracts, update the spec as part of the work.
