Add stream-android-core-ui with the shared design tokens - #84
Conversation
The module holds the core design tokens as immutable Compose classes so the Chat and Video Compose themes can share them: StreamDesign (Colors, ColorScale, ChromeScale, Typography), StreamTokens and the internal StreamPrimitiveColors. It depends on compose-runtime, foundation, ui-graphics, ui-text and ui-unit only, with the Compose BOM published as an imported BOM in the POM. The classes come from the vendored layer in stream-video-android, with the package changed and the derived component tokens on Colors made public, since consumers now sit across a module boundary. The token source is the tokens/core namespace of GetStream/design-system-tokens, including the typography and option card radius fixes from #76.

91-91: 🗄️ Data Integrity & Integration | 🔵 Trivial | 🏗️ Heavy liftKeep future token additions off constructor and
copysignatures.
Colors,ColorScale,ChromeScale, andTypographyexpose data-class constructors andcopymethods whose JVM descriptors include their primary-constructor properties. Adding a token changes those descriptors. An already compiled Chat or Video call site that invokes an old constructor orcopycan throwNoSuchMethodErrorwhen it runs with the newer artifact. Appending a property does not invalidate existingcomponentNmethods.
AGENTS.mdallows signature breaks when coordinated with version bumps, and this module and API dump are new in this PR. This is a future compatibility cost, not a break to an existing API. If token additions should remain binary-compatible, use regular@Immutableclasses with private constructors and stable factories or builders. Poko alone does not address the public constructor’s changing descriptor.🤖 Prompt for AI Agents

bright brands use a contrasting foreground for both light and dark themes,
rather than always inheriting white from `Colors.default` or

appropriate, and add tests covering bright-brand contrast in both themes.

Looks good, I left mostly minor comments. The one thing I think is most important overall is to add annotation so we better define the public API boundary for the tokens.
…e api scope - Annotate StreamDesign and StreamTokens with @StreamPublishedApi and the derived color tokens with @StreamInternalApi. - Expose the radius tokens as Dp, with 9999.dp for radius-full as in the token source, so the module no longer needs foundation. - Move the Compose BOM to the api scope so the api variant of the Gradle module metadata carries the versions. - Include the module in coverage and fix KDoc copied from the wrong token.
