Cross (Native Bridge Library)
=============================
Cross is a static C library (`libcross.a`) that provides native helper
functions for a dynamically loaded world to interact with the runtime and
wlroots.
Why a static library?
---------------------
These helpers are linked into the world (`.so`) so they hot-reload along with
the world, instead of being stuck inside the long-running runtime process.
API surface
-----------
Public headers live in `cross/include`.
- `cross/include/util.h`: world-facing functions used via FFI, including:
- runtime requests (log/exit/hot-reload)
- seat access
- toplevel queries and basic positioning/geometry helpers
Building
--------
Cross is built via the top-level CMake project:
```sh
cmake -S .. -B ../build
cmake --build ../build --target cross
```
