Detailed Description

Block descriptor. For overflow blocks this struct is stored at the start of the heap allocation itself (co-located), so each new block costs one call to aligned_alloc_xp instead of two. The usable region begins at block->base.

The first block uses first_block inside Arena and points into a caller- or TLS-provided buffer, so is_static is set and its memory is never freed.
