// --- Core API ---
export { prepare, prepareWithSegments } from './prepare'

// --- Rich Inline (formerly inline-flow) ---
export { prepareInlineFlow, walkInlineFlowLines, measureInlineFlow } from './rich-inline'

// --- Obstacle Layout ---
export {
  carveTextLineSlots,
  circleIntervalForBand,
  rectIntervalForBand,

// --- Zoom ---
export { computeZoomLayout } from './zoom'

// --- Animated (requires react-native-reanimated) ---
// Import from 'expo-pretext/animated' to avoid requiring reanimated for non-animated usage:
//   import { useAnimatedTextHeight, useCollapsibleHeight, usePinchToZoomText } from 'expo-pretext/animated'
// Or import directly from hook files:
//   import { useAnimatedTextHeight } from 'expo-pretext/src/hooks/useAnimatedTextHeight'
