Static	Protocol Data (embedded in .data section)
These	structures are defined at fixed addresses in the PE .data section.
The	following extern declarations allow the code to reference them.
Defined	at absolute address 0x40B0 (after GUID header).
Defined	at absolute address 0x40D8.
Defined	at absolute address 0x9020.
gPlatformProtocol	is lazy-init via GetPlatformProtocol().
If	it's NULL, LocateProtocol hasn't succeeded and we skip.
GetPlatformProtocol	();

Return	cached value if already resolved.

Health	check: allocate 31 bytes as a pool probe.
PoolProbe	= (UINT64)gBootServices->AllocatePool (31);
Free	the probe allocation immediately.
If	pool returned > 0x10 bytes, allocator is healthy -> LocateProtocol.
if	(PoolProbe <= 0x10) {
Locate	the platform protocol by GUID.
If	LocateProtocol failed, ensure we return NULL.
