Patch Changes

• 863cc86: Typography and TextSpan — the first entry of the v1 core

  Ten roles, aligned with the reference implementation's text: h1–h6, body, body-sm, body-xs and code. Each role fixes size, line height, weight and family together, which is why there is no size prop and no weight prop — the combinations they allowed (a heading in a light weight, a caption in a display size) become unwritable rather than discouraged.

  TextSpan is a bare React Native Text. Nesting a Text inside a Text already inherits font, size, weight and colour on both platforms, so a span needs no context to read and no role to resolve: the legacy TextSpanContext was reimplementing the platform, and it is gone. Typography therefore publishes no slot and does none of a span's work.

  Neither alignment nor truncation gets a prop. textAlign is a TextStyle key that R14 already exposes, and numberOfLines is React Native's own — a prop of ours would be a second name for the same thing.
