🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Cover the brand color atom.

brand is a new TypographyColor value, but this table omits it. Include brand so a broken colors.brand mapping cannot ship without a failing test.

As per coding guidelines, "Unit tests are required for all new functionality."

In `@packages/ui/src/mosaic/components/text/text.test.tsx` at line 44, Update the
parameterized color test in the typography text tests to include the new brand
value alongside foreground and foreground-secondary, ensuring the existing
color-atom assertions also validate the colors.brand mapping.
