Smart currency field

Formats monetary input while preserving caret-friendly editing and showing a fee calculation. Input sanitizes decimals, formats on blur, and updates fee and net values as text. Adds locale-aware monetary derivation rather than a generic text field.

Accessibility notes

  • Every interactive target is a labelled native control with a visible focus treatment.
  • State changes are communicated through a polite text status and never by color alone.
  • The contained visual effects stop when the user requests reduced motion.
