Independent Quality Control (QC) & Verification Suite

Verifies:
|

1. File existence for all 21 screenshot targets
|

2. Exact resolution: 1440x900
|
||||
3. Non-trivial file size: > 10 KB
|
||||
4. Visual complexity / non-blank entropy: > 2.0
|
||||
5. Pairwise SHA-256 uniqueness across all 21 files (ZERO hash collisions)
|
||||
6. Element / viewport distinctness for critical pairs (e.g. 08 vs 12, 10 vs 11 vs 13, 17 vs 21)
|
||||
7. Automatically updates and writes screenshots/QC_REPORT.md
