REFERENCE TABLES
Layer | Required definition
Creative master | 3072 × 1536 pixels for the wall-specific image
Transport | 3840 × 2160; native image starts at (384, 312)
Input region | x=384, y=312, width=3072, height=1536
Physical map | 3072 × 1536; no further size conversion for this example
Observed symptom | Next discriminating check
Missing border | Inspect crop, input origin and output region before changing the content
Soft fine detail | Trace every stage that can resize, including application output and GPU scaling
Correct geometry, coloured text edges | Check signal colour sampling and the source artwork separately
Correct local view, patterns on camera | Separate spatial moiré from camera timing artefacts; do not remap the wall solely from a camera image
