Core

The lowest-level primitives of the Opal design system. Think of core like Rust's core crate — compiler intrinsics and foundational types — while higher-level modules (like Rust's std) provide the public-facing components that most consumers should reach for first.

End-users can use these components directly when needed, but in most cases they should prefer the higher-level components (such as Button, OpenButton, SelectButton, etc.) that are built on top of core.
