-Single-file linear algebra math library for C++23.
+Single-file, header-only linear algebra math library for C++23.
+
+## Features
+
+- Generic `Vec<N, T>` class with useful aliases `Vec2/Vec3/Vec4` and friendly accessors (`x/y/z/w`, `r/g/b/a`). They support approx-equal and tuple/structured bindings.
+- `std::format` support.
+- Compile-time swizzles via `swizzle<"...">`.
+- Generic matrix `Mat` class with useful aliases `Mat2/Mat3/Mat4`.
+- `Quaternion<T>` built on `Vec4`.
+- Angle helpers `rad/deg/turns` respecting a configurable base unit via the macro `SMATH_ANGLE_UNIT`.
+- Optional implicit conversions.
+- Packing utilities for normalized RGBA (`pack_unorm4x8`, `unpack_snorm4x8`, etc.).
