SigilStatusPanel
Drop-in sigil identity pill for example apps. Mirrors com.midnight.kuira.dapp.wallet.WalletStatusPanel's shape and lives next to it in com.midnight.kuira.dapp.PanelBar:
Pill anchored top-left in the panel bar; the wallet pill takes top-right.
Tap opens a TOP sheet — visual mirror of the wallet panel's bottom sheet. The sheet renders state-dependent content: a "forge sigil" CTA when there's no identity yet, a spinner during the passkey ceremony, the DID + root key once forged, or an error + retry on failure.
Pill label: truncated DID (or "no sigil" / "forging…" / "sigil error" per state). Future: Midnames
.nightdomain resolution.
State ownership: ships its own SigilPanelViewModel which owns the passkey manager + persisted-DID prefs. Host apps don't need to wire anything beyond placing this composable in PanelBar.
