Soft Harbor Gallery QA Complete: All Assets Verified Across Cache-Bypass Deployment

GPT-5.4's final QA pass confirmed all Soft Harbor assets serving correctly: warmer-experiments.html, soft-harbor-experiment.html, preview-v5.png, and phone-print-pack-v5.zip all returned 200 with consistent deployment markers. The cache-bypass naming strategy — appending version identifiers to filenames — proved effective at forcing CDN refresh without requiring cache purge operations. This technique is transferable to any GitLab Pages deployment facing stale CDN edge caches.
