+Purpose:
+  Normalize and enforce AMD two-line copyright + SPDX headers across files.
+
+Target files:
+  - C/C++-style: .cpp, .hpp, .inc  -> uses "//" comment style
+  - Hash-style:  .py, .cmake, .sh, and CMakeLists.txt -> uses "#" style
+
+Header formats inserted (top of file, followed by exactly one blank line):
+  C/C++  :
+    // Copyright (c) Advanced Micro Devices, Inc., or its affiliates.
+    // SPDX-License-Identifier: MIT
+    <blank>
+  Hash   :
+    <blank>
+
+Shebang special case (hash-style only):
+  - If line 1 starts with "#!", keep shebang, then a blank line, then the
+    two hash-style header lines, then a blank line.
+
+Removal rules:
+  - Remove any comment lines (anywhere in file) containing the keywords
+    "copyright" or "spdx" (case-insensitive). Blank lines are preserved.
+  - Remove long-form MIT license block comment when:
+      a) The file starts with the block (absolute top), OR
+      b) The block appears immediately after the AMD header position
+         (i.e., when remainder at insertion point begins with "/*" and
+         the first content line is "* The MIT License (MIT)").
+
+Blank-line normalization:
+  - Enforce exactly ONE blank line immediately after the AMD header.
+    (Drop only the leading blank lines at the insertion point before
+     re-inserting the header.)
+  - Do not change blank lines between other non-copyright comments.
+
+Preservation:
+  - Preserve original newline style: CRLF (\r\n) vs LF (\n).
+  - Preserve UTF-8 BOM if present.
+  - Do not modify non-comment code lines.
+
+Idempotency:
+  - Running this script multiple times does not further modify files.
