## Technical Achievements

### WASM Optimization

**Cargo.toml Configuration** (Already Present):
```toml
[profile.release]
opt-level = 3          # Maximum optimization
lto = true             # Link-Time Optimization
codegen-units = 1      # Single codegen unit
strip = true           # Strip debug symbols

[profile.release.package.wasm-opt]
opt-level = "z"        # Size optimization
```

**Expected Bundle Sizes**:
