### Naura (mid)  → /naura.md

### ASML (mid)  → /asml.md
- note: Mature-node lithography depends on ASML DUV (193nm immersion) — EUV is banned for China, DUV needs a 2023 Dutch dual-use license, and the April 2026 MATCH Act specifically targets Hua Hong (including service/support). This upstream dependence caps advancement and expansion.
