Use the CanoKey for daily authentication on idols-ai and shoukei, with the existing passwords, passphrases and per-host SSH keys as fallback. - sudo: pam_u2f with a shared origin (pam://ryan4yin) and a Nix-store authfile built from myvars.canokeyU2fKeys; the primary key is registered and touch-to-sudo works on idols-ai. - SSH: one resident ed25519-sk key (application=ssh:ryan4yin) exported to ~/.ssh/id_ed25519_sk; GitHub tries it before the per-host key. - shoukei LUKS: fido2-device=auto with token-timeout=10s. Update nixos-apple-silicon (linux-asahi 7.2.14), whose initrd adds thunderbolt_apple and reset_apple_cio so USB-C comes up before unlock. - GPG: scdaemon disable-ccid so it uses pcscd. - docs/security-keys.md: setup, PINs, enrollment, backup key and recovery; deduplicate the FIDO notes left by #515.
