Core domain types, port traits, and schema validation for the
[Odal Node](https://odal-node.io) Digital Product Passport system.

This is the foundational crate. All other `dpp-*` crates depend on it.
It contains everything that changes when EU regulations change — and nothing else.

## When to use this crate


- You need the DPP data model: `Passport`, `SectorData`, `TransferChain`.
- You are implementing a platform adapter (database, HTTP layer) and need the
  port trait interfaces: `PassportRepository`, `IdentityPort`, `PluginHost`, etc.
- You want to validate passport data against embedded JSON schemas.

## Example


```rust
use dpp_domain::{Passport, PassportId, Sector, SectorData, TextileData, FibreEntry};

let passport = Passport::new(
    PassportId::new(),
    "did:web:manufacturer.example.com".into(),
    Sector::Textile,
    SectorData::Textile(TextileData {
        fibre_composition: vec![FibreEntry {
            fibre_type: "Organic Cotton".into(),
            percentage: 100.0,
            country_of_origin: Some("TR".into()),
        }],
        care_instructions: "Machine wash 30°C".into(),
        country_of_manufacture: "TR".into(),
        ..Default::default()
    }),
);

passport.validate().unwrap();
```
