The iOS chrome inherited macOS dialog sizing and read as undersized on a phone: - Toolbar: the two trailing actions shared one compact glass pill; on iOS 26+ each now gets its own full-size circle (explicit .topBarTrailing placements split by a fixed ToolbarSpacer — the system-app look, e.g. Files), with the grouped-pill fallback on iOS 17–18. The buttons are extracted so macOS keeps SettingsLink + .help untouched. - Sheets and CTAs (AddHostSheet, PairSheet, trust card, empty-state Add Host) get .controlSize(.large) on iOS — proper touch targets instead of macOS dialog buttons. Verified in the iPhone 17 simulator: two ~44 pt glass circles matching the Files app's toolbar sizing; macOS suite and app build unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

// Hosts grid ⇄ trust prompt ⇄ live stream.
|
||
//
|
||
// Home is a grid of saved hosts (click to connect); "+" in the toolbar adds one; the
|
||
// stream mode lives in Settings (⌘,). Two ways to establish trust on first contact:
|
||
// the TOFU prompt (host fingerprint over the live-but-blurred stream, user compares it
|
||
// with the host's log) or the PIN pairing ceremony (right-click a card → "Pair with
|
||
// PIN…", or from the trust prompt itself) — pairing verifies both sides at once and is
|
||
// the only way into hosts running --require-pairing. Once pinned, reconnects are silent
|
||
// and a changed host identity refuses to connect.
