Deploy HickLab3D Dashboard / Deploy to production (push) Failing after 23s
Replace the old touchmark/PNG identity with the supplied lockup and monogram, segmented role-aware navigation, Live/Draft listing filters with generation-based cache invalidation, and admin Projects covering immutable file revisions, listing live pointers, and exact-decimal filament/packaging/shipping costing. Additive schema only; no Etsy publication. Isolated clone tests: 301 tests, 1162 assertions.
