-| **ReScript** | Primary application code | Compiles to JS, type-safe |
+| **AffineScript** | Primary application code | Affine-typed, compiles to typed-wasm or ESM |
 | **Bun** | JS runtime & package management (tier 1) | Default for all new work. Runs compiled ESM/JS directly — no bundler step. Uses an npm-compatible `package.json` plus `bun.lock` — both are expected, not anti-patterns. |
 | **Rust** | Performance-critical, systems, WASM | Preferred for CLI tools |
 | **Tauri 2.0+** | Mobile apps (iOS/Android) | Rust backend + web UI |

 2. **Use `package.json` + `bun.lock` for JS runtime deps** - Bun is npm-compatible; a manifest is REQUIRED
 3. **`bun install --production --frozen-lockfile` for production deps** - resolved from `package.json` and pinned via `bun.lock`; `--frozen-lockfile` makes a lockfile mismatch a build failure rather than a silent re-resolve
