scalar.constant.ts

A scalar constant defines the shape of a small reusable value. It should be simple enough to understand without reading a service, signal, or store file.

Most scalar constants need only `via()`, `field()`, optional defaults, and sometimes a small enum.

Basic Shape

Use `via((field) => ({ ... }))` and describe each value with `field(Type)`. The class name should describe the business value, not the parent model that happens to use it.

Defaults And Optional Fields

Add defaults when a value should have a stable initial state. Use `.optional()` when the parent model can exist without that field.

`currency` can default to a normal business value such as `KRW`.
`memo` can be optional because not every price needs a note.

Array Fields

Use an array field when the scalar naturally contains a repeated value. Keep the example small: a contact info value may have several emails.

Enum Fields

Use `enumOf()` when a field should only allow a fixed set of values. The enum name string is also used by the dictionary file, so keep it short and stable.

Small Helpers

A constant may include a small pure helper when the behavior belongs to the value itself. Keep it independent from server requests, database calls, and external services.
