/**
 * Detects iOS/iPadOS Safari to work around a VoiceOver bug that blocks
 * interaction with date-related inputs.
 * @see https://dev.to/mfranzke/voiceover-bug-on-ios-safari-blocks-date-time-related-inputs-especially-in-react-4f61
 *
 * Known limitations:
 * - iOS WebViews (in-app browsers like Instagram, Facebook) use WebKit and may
 *   be affected by the same bug, but are not detected here since they don't
 *   include "Safari" in the user agent string.
