chore: normalize SPDX source copyright headers

 - TypeScript strict mode
 - We end lines with semicolons
 - Single quotes
+- First-party source files with `SPDX-License-Identifier` must also declare each actual copyright holder using `SPDX-FileCopyrightText`.
+- Preserve existing license expressions and upstream attribution; do not infer MIT licensing or ownership for generated, vendored, or third-party files.
 - Never abbreviate variables, always type out the full name in camelCase (variables, functions, fields), PascalCase (types), CAPITAL_CASE (constant)
 - Prefer verbNoun structure for function and method names.
 - Keep shipped runtime validation minimal to protect bundle size. Prefer static typing and simple assertions over heavy validation or verbose runtime error paths.

 ## Attribution
 
-This implementation of PBR (Physically-Based Rendering) is a fork of the [Khronos Reference Implementation](https://github.com/KhronosGroup/glTF-WebGL-PBR) under the Apache 2.0 license.
+The GLSL and WGSL material shaders derive from the historical
+[Khronos glTF-WebGL-PBR reference shader](https://github.com/KhronosGroup/glTF-Sample-Viewer/blob/88eda8c5358efe03128b72b6c5f5f6e5b6d023e1/shaders/pbr-frag.glsl).
+The version incorporated into luma.gl was distributed under the
+[MIT License](https://github.com/KhronosGroup/glTF-Sample-Viewer/blob/88eda8c5358efe03128b72b6c5f5f6e5b6d023e1/LICENSE.md)
+with `Copyright (c) 2016-2017 Mohamad Moneimne and Contributors`. Both shaders preserve that
+upstream copyright alongside the vis.gl contributors' additions and remain MIT-licensed.
+
+The upstream project has since been renamed
+[glTF Sample Viewer](https://github.com/KhronosGroup/glTF-Sample-Viewer), and its current releases
+use the [Apache License 2.0](https://github.com/KhronosGroup/glTF-Sample-Viewer/blob/main/LICENSE.md).
+That later license does not replace the MIT terms attached to the historical version used here.
