Macro include_vmfb 

macro_rules! include_vmfb {
    ($path:expr) => { ... };
}

Embed a compiled .vmfb as a 64-byte-aligned &'static [u8].

IREE’s FlatBuffer verifier requires the module header to be aligned, and, critically, the rodata segments (model weights) inside are only used in place when they meet HAL buffer alignment (64 bytes). An underaligned module silently falls back to staging copies through the device queue, which costs RAM and deadlocks the bare-metal single-threaded HAL. A plain include_bytes! (1-byte aligned) guarantees neither; use this for any embedded model.
