Could you add tests for some cases like these?
```
if (__builtin_available(anyAppleOS 26.0, macos 27.0, *)) { ... }
if (__builtin_available(macos 27.0, anyAppleOS 26.0, *)) { ... }
if (__builtin_available(anyAppleOS 27.0, macos 26.0, *)) { ... }
```
The most specific active platform should take priority, I assume, like with
`maccatalyst / ios`.
