//! Field action handling for interactive forms according to ISO 32000-1 Section 12.6.3
//!
//! This module provides support for field actions including:
//! - Focus events (Fo) - when a field receives focus
//! - Blur events (Bl) - when a field loses focus  
//! - Format events (F) - before displaying value
//! - Keystroke events (K) - during text input
//! - Calculate events (C) - after field value changes
//! - Validate events (V) - before committing value
