Expand description
Frame-scoped bump allocation.
A FrameArena is a fixed block of bytes with a bump pointer. Per-frame
transient data — visible-instance lists, draw arguments, scratch index
buffers — is carved out of it and thrown away wholesale by FrameArena::reset
at the frame boundary. No per-allocation bookkeeping, no free, no
fragmentation.
