+
+**Date**: 2026-08-04
+**Task**: Add configurable area asset budgets
+**Branch**: `main`
+
+### Summary
+
+Added configurable GLB budgets with documented exceptions, shared budget evaluation for diagnostics, quality gates, and Cesium/compress manifests, plus render-triangle, embedded-image, and source attribution diagnostics. Verified budget tests, preflight tests, nantaizi diagnostics/check, and a controlled low-budget failure without running heavy stages.
