Component registry

Tracks the status, specification, and key details of every component in the design system. Agents MUST check this before building a component (to avoid duplicates) and MUST update it after completing one.

Status definitions

• planned: Component is identified but not yet started
• in-progress: Component is being built
• review: Component is built, awaiting human review
• done: Component is reviewed and approved
• needs-revision: Component needs changes based on review feedback

Future enhancements

Deferred items that should be addressed when the relevant components or patterns are needed. Check this section before building new components — an item here may be relevant to your current work.

Item	Relates to	Trigger	Notes
Destructive button colours	Button	When building delete/cancel flows	color="error" already works via MUI palette. May need soft variant styling for error/warning/success colours.
Link-as-button	Button	When building Navigation or link-heavy pages	Use MUI's component="a" or href prop. May warrant a separate Link atom or a Button story showing the pattern.
IconButton atom	IconButton	When building Navigation, modals, toolbars	Wrap MUI IconButton with FA theme tokens. Registered as planned atom above.
Google Fonts loading	Typography	Resolved	Added to .storybook/preview-head.html and index.html
