Crate confium_store_openpgp_card 

OpenPGP card backend (YubiKey OpenPGP applet, Nitrokey, Gnuk).

Standards-only: uses the OpenPGP card v3+ spec. No vendor-specific SDKs. All OpenPGP-compatible smartcards work.

The OpenPGP card spec natively supports:

• SIG slot (signing)
• DEC slot (decryption)
• AUT slot (authentication)

Real hardware integration requires openpgp-card + card-backend-pcsc crates, which depend on PCSC. This crate provides the trait interface and an in-memory mock backend for testing.

See TODO.roadmap/34-identity-and-hardware.md for full spec.
