Johan Persson 539cf2690a feat(ui): migrate Avatar from Base UI with updated size scale
Removed Base UI dependency from Avatar component and reimplemented
with native HTML elements. Updated size scale with new x-small and
x-large options.

Breaking changes:

- Base UI-specific props (render, etc.) are no longer supported
- Component now uses native div/img elements instead of Base UI primitives
- Size scale updated: large changed from 3rem to 2.5rem
- Added x-small (1.25rem) and x-large (3rem) sizes

Migration:

- <Avatar src="..." name="..." render={...} />
+ <Avatar src="..." name="..." />

- <Avatar size="large" />
+ <Avatar size="x-large" />

New features:

- Added purpose prop with 'informative' (default) and 'decoration' options
- Informative avatars announce name to screen readers
- Decorative avatars hidden from screen readers (use when name appears adjacent)
- Five size options: x-small, small, medium, large, x-large

Documentation updates:

- Updated size examples to show all five sizes
- Added Purpose story and documentation
- Updated prop definitions and usage examples
- Updated changeset with migration guide for size changes

What is Backstage?

Backstage is an open source framework for building developer portals. Powered by a centralized software catalog, Backstage restores order to your microservices and infrastructure and enables your product teams to ship high-quality code quickly without compromising autonomy.

Backstage unifies all your infrastructure tooling, services, and documentation to create a streamlined development environment from end to end.

software-catalog

Out of the box, Backstage includes:

  • Backstage Software Catalog for managing all your software such as microservices, libraries, data pipelines, websites, and ML models
  • Backstage Software Templates for quickly spinning up new projects and standardizing your tooling with your organizations best practices
  • Backstage TechDocs for making it easy to create, maintain, find, and use technical documentation, using a "docs like code" approach
  • Plus, a growing ecosystem of open source plugins that further expand Backstages customizability and functionality

Backstage was created by Spotify but is now hosted by the Cloud Native Computing Foundation (CNCF) as an Incubation level project. For more information, see the announcement.
