VariableSchema class

Authoring metadata for one {{ name }} placeholder a campaign declares.

Two lists in templateConfig declare them, and both parse to this type:

• variables — custom variables, named in lowercase (coupon).
• contextVariables — a Digia-managed campaign's user attributes and event properties, named by their token (user.age, event.orderValue).

type determines how the value is handled at render time:

• "string" — substituted as-is.
• "number" — printed like 199 rather than 199.0, and usable in arithmetic expressions inside {{ }}.
• "bool" — printed as true / false. Only context variables use it.

fallbackValue is the dashboard-declared default. sampleValue is a legacy alias of fallbackValue that the dashboard still writes. Null means no fallback.
