The card's name renders as part of the card body, so the chrome said it
twice. HostedWindowController gains a titleVisibility slot on the same
retained-slot pattern as the accessory and toolbar (reapplied at attach,
so the macOS 26 provisional-window swap can't lose it); CardWindowHost
opts in beside installToolbar, board windows keep AppKit's default.
window.title itself is untouched — navigationTitle still feeds the
Window menu, Exposé, VoiceOver and restoration.
Known consequence, probed empirically: under .hidden AppKit collapses
title and subtitle into one hidden field, so the "board › lane"
navigationSubtitle disappears with it — and the details sidebar carries
no placement rows, so a card window currently shows its home nowhere.
Filed on the Redesign board to bless or relocate; 05-card-window.md's
subtitle sentence needs reconciling either way.
