+- Playwright browser downloads on every build (~400MB)

-### After Multi-Stage

+## Advanced Optimizations in Base Image
+
+### Pre-installed Development Tools
+**Python Tools** (cached in `/opt/python-dev-tools/`):
+- `ruff` - Fast Python linter/formatter
+- `pyright` - Python type checker
+- `pytest` + plugins - Testing framework
+- `pre-commit` - Git hook framework
+- `yamllint`, `toml-sort` - Configuration file tools
+
+**Node.js Tools** (installed globally):
+- `typescript` - TypeScript compiler
+- `eslint` - JavaScript/TypeScript linter
+- `prettier` - Code formatter
+- `vite` - Build tool
+- `@types/node` - Node.js type definitions
+
+**Benefits**:
+- **Compilation Cache**: No more compiling these tools from source
+- **Dependency Resolution**: Faster yarn/uv install due to fewer packages
+- **Network Efficiency**: Less download bandwidth per build
+- **Build Reliability**: Stable tool versions cached in base
+
+### After Multi-Stage (Fully Optimized)
+- Base image build: ~20-25 minutes (only when base changes, includes browsers + dev tools)
+- Complete image build: ~2-3 minutes (reuses cached base with everything pre-installed)
+- **Typical CI run**: ~2-3 minutes (98% of runs use fully cached base)
+- **Major wins**: No browser downloads (~400MB), no dev tool compilation, faster dependency resolution
