+# cimery — WASM/PWA build (Sprint 22, ADR-001 dual-target)

+# Constraints:
+#   - OCCT is NOT available for WASM (--features occt excluded)
+#   - Target: wasm32-unknown-unknown
+#   - Packager: wasm-bindgen-cli
+#
+# Build output: pkg/ directory → deploy to Cloudflare Pages (cimery-web.pages.dev)
