  3. Stable Class Combo: button.primary.large (avoids hashed/dynamic classes)
  4. ARIA Attributes: [role="button"], [aria-label="Close"]
  5. Semantic Elements: input[name="email"], button[type="submit"]
  6. Contextual :has() (when applicable): e.g. label[for="id"]:has(+ input)
  7. Hierarchical Path: nearest‑ID path using :nth-of-type when needed
