- Removed global renderer, camera, and scene management in favor of layer framework integration.
- Implemented terrain layer registration with setup, render, and dispose methods.
- Enhanced texture loading and caching mechanisms.
- Updated geometry building to return Mesh objects directly.
- Added performance benchmarking story for render performance validation.
- Created bundle size audit story to ensure effective tree-shaking and size constraints.
- Implemented registration of draw-relief-icons with WebGL2LayerFramework, removing module-level renderer state.
- Updated drawRelief, undrawRelief, and rerenderReliefIcons functions to utilize framework methods.
- Ensured SVG fallback path is preserved and functional.
- Added performance criteria for rendering relief icons.
- Created tests to verify fallback integration and visual parity with existing SVG output.
test: Add WebGL2 fallback integration verification
- Introduced new tests for WebGL2LayerFramework to ensure no-ops when fallback is active.
- Verified that drawRelief routes to SVG when WebGL2 is unavailable.
- Confirmed visual parity between SVG output and existing implementation.
- Ensured all tests pass with updated coverage metrics.
