// uniform clipboard types. the expo-clipboard module api is the reference
// shape so migration stays mechanical; function names are rewritten by the
// api-conventions fixed rule (async suffix dropped): getStringAsync is
// getString, addClipboardListener is addListener with the namespace noun
// dropped.
