Terse lookup. **(dual)** = acts immediately when fully applied, returns a Gomega matcher when under-applied (poll with `Eventually`). **(matcher)** = always returns a matcher. **first** = acts on the first match; **each** = acts on all matches (empty slice when none). Selectors are CSS strings or `XPath` (see `biloba:xpath`). Full docs: <https://onsi.github.io/biloba/>.
