Crate orthotope 

Orthotope is an arena-backed allocator with fixed size classes, per-thread caches, a shared central pool, and a tracked large-allocation path.

Use allocate and deallocate for the process-global convenience API, or construct an Allocator plus one ThreadCache per participating thread for direct instance-oriented use. Downstream binaries may also opt in to a #[global_allocator] adapter via OrthotopeGlobalAlloc.

Only free live pointers returned by Orthotope. Debug builds detect some small-object double frees, but same-arena pointer forgery and stale-pointer ABA cases are still outside the allocator’s guaranteed provenance boundary.
