Detailed Description

Standalone rendering integration test for Donner on WASM.

Verifies that the full Donner pipeline (parse → style → shape → render) produces correct pixel output. Tests three layers:

1. Direct tiny_skia rasterizer (isolates rendering backend)
2. CSS Color::ByName lookup (tests CompileTimeMap on 32-bit targets)
3. Full SVG parse + render (end-to-end integration)

Build & run natively: bazel run //examples:render_test

Build & run as WASM: bazel build –config=wasm //examples:render_test_wasm node bazel-bin/examples/render_test_wasm/render_test.js
