Forms are inherently stateful — idle, validating, submitting, success, error. A state machine makes these states explicit and prevents invalid transitions.

• Form states: idle → validating → submitting → success / error

• Guard conditions for validation rules

• Nested states for multi-step wizards

• Context for form data

• Forms → Data Fetching — Async form submission

• Forms → Undo/Redo — Undoable form edits

• Forms → Navigation — Form wizard routing

• Learn: Patterns — Learning path

• XState + React — React implementation

• Case Study: Checkout — Real-world example

• Add complete machine definition for multi-step form

• Add validation state machine example

• Add wizard navigation machine
