Function attributeDeclaredFields

attributeDeclaredFields(def: Readonly<Record<string, unknown>>): DeclaredField[]
The attribute fields a layer SHOWS, under feature-info's reading rule (resolvePath over the normalized { properties, attributes } model).

Only a field that declares display.surfaces is judged: a capture-only field (an edit block and no display) is filled when a feature is created, and its absence from the loaded data is normal, not a fault. titleField is not a data read — it names one of fields[] —, so it is not judged here either.
Parameters
- def: Readonly<Record<string, unknown>>
  A layer definition.
Returns DeclaredField[]
One declared field per displayed attribute; none when the layer declares no attributes block.
Example
```
attributeDeclaredFields({ attributes: { fields: [
    { field: "properties.NAME", label: "Nom", display: { surfaces: ["popup"] } },
] } });
// → [{ key: "attributes.fields[0].field", field: "properties.NAME", present: … }]
```
