// 🤖 The Threads list, as an iOS sheet: this chat's threads, freshest first,
// one row per thread root. The list itself is LChatCore's ReplyThreadListView
// (shared with the Mac's docked column, so the rows and their accessible names
// are word for word the same); this file is only the sheet chrome around it —
// the title, the Done button, and the dismissal a tapped row rides out on.
//
// Why a sheet rather than a column: the iPhone has no room for a second one,
// and a tapped row lands in the thread pane (iPad) or the lifted thread
// overlay (iPhone) — so the list is a transient index you come out of, exactly
// like Media, Links & Docs. That also matches the web's single-right-dock
// rule: finding the thread and reading it are never both on screen.
struct ThreadListSheet: View {
    @ObservedObject var model: ChatFeedModel
    /// Open this thread. The screen dismisses the sheet first, then opens the
    /// thread the same way a "N Replies" tally tap does.
    let onOpen: (Int64) -> Void
    @Environment(\.dismiss) private var dismiss
    // The reader's chosen colour theme, so a row highlights in the same
    // bubble tint the feed behind the sheet uses.
    @AppStorage("nativeTheme") private var themeName = "classic"

    var body: some View {
        NavigationStack {
            // The sheet's navigation bar carries the title and Done, so the
            // shared view draws no header of its own.

                                onClose: { dismiss() })
