// 1. IMAGE_DOS_HEADER — DOS MZ magic + e_lfanew offset.
// 2. IMAGE_FILE_HEADER — section count, machine type, timestamps.
// 3. IMAGE_DATA_DIRECTORY — export/import/etc directory RVAs.
// 4. IMAGE_OPTIONAL_HEADER64 — SizeOfImage@56 (not 36 — that bit us for hours).
// 5. IMAGE_SECTION_HEADER — .text, .data, .rdata layout per section.
// 6. IMAGE_EXPORT_DIRECTORY — name/function/ordinal tables for PE export parsing.
// 7. IMAGE_NT_HEADERS64 — signature + file_header + optional_header (the NT header triad).
