Selector Priority

The tool generates selectors in this priority order:

ID: #unique-id (most reliable)
Data Attributes: [data-testid], [data-cy], [data-test]
Stable Class Combo: button.primary.large (avoids hashed/dynamic classes)
ARIA Attributes: [role="button"], [aria-label="Close"]
Semantic Elements: input[name="email"], button[type="submit"]
Contextual :has() (when applicable): e.g. label[for="id"]:has(+ input)
Hierarchical Path: nearest‑ID path using :nth-of-type when needed
