- Introduced `LayersModule` to handle layer registration, visibility, and ordering.
- Created `WebGLSurfaceLayer` and `SvgLayer` classes to encapsulate layer behavior.
- Refactored `TextureAtlasLayer` to utilize the new layer management system.
- Updated HTML structure to accommodate new SVG and canvas elements.
- Ensured all TypeScript checks pass with zero errors on modified files.
- Added documentation for Story 1.6 outlining the requirements and acceptance criteria for migrating shared defs-backed resources to a dedicated host.

- 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.
