详细描述

Per-frame GPU allocation arena (host-visible coherent).

One arena per swapchain frame slot. reset() at frame start; alloc() hands out monotonically increasing offsets until capacity. There is no free/realloc inside a frame: everything written here lives until the slot wraps around, which is exactly the lifetime the frame's command buffer needs.
