Heap Memory

The dynamic memory region available to SBF programs during execution, defaulting to 32KB. Programs use heap memory for dynamic allocations (Vec, String, Box). The heap size can be increased up to 256KB by requesting additional compute units via the Compute Budget Program's RequestHeapFrame instruction. Heap exhaustion causes the program to fail with an AccessViolation error. Efficient programs minimize heap usage through zero-copy patterns and stack-allocated buffers.
