- Add wasm_stubs.cpp with WASM-specific stub implementations for COLOR4D::BLACK/WHITE, GLU tesselator, PGM_BASE, and other KiCad dependencies - Update Makefile to include KiCad sources (GAL base class, display options, HiDPI canvas) and test scenarios - Fix kiglew.h to define GLEW guard (__glew_h__) preventing conflicts with Emscripten's GLEW header - Update test HTML to create canvas before module load (MODULARIZE requires passing canvas in Module config, not preRun) - Update Playwright tests to find canvas elements correctly - Add #window-container for wxWidgets GL canvas support Build produces 8.4MB WASM with full WEBGL_GAL implementation. Tests pass but rendering still shows dark output (debugging in progress). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
