Geometry inline, texture out of line: the image is a relative URI to a sibling PNG while the buffer is embedded, which is the mixed layout that trips asset packers expecting all-or-nothing. Download the PNG in this group with it.
The 64x64 two-colour checker referenced by the external-texture glTF in this group. Small, hard-edged and axis-aligned on purpose: UV seams, wrap mode and filter choices are all visible at a glance.
The same textured sphere with the PNG inlined as a base64 data URI in `images[0].uri` — a single portable text file. The variant that makes a glTF e-mailable and that some loaders quietly refuse.
The third texture-storage strategy: the PNG lives inside the GLB's BIN chunk as a bufferView, addressed by `mimeType` rather than a URI. This is what a GLB packer must produce, and extracting the image again is the round-trip test.
