rzen b0ffff1aa1 The app learns Appearance — Auto, Light, Dark from the View menu and a toolbar pull-down
View ▸ Appearance (11-command-nexus.md): three radio-exclusive rows,
app-wide, persisted, needing no window in front — the View menu's new
last group. AppearanceStore owns the override's rules (absent key =
Auto, lenient reads degrade to Auto, remove-at-default) with an
injectable apply seam so test hosts never touch NSApp; the one real
apply hands NSApp.appearance its answer in applicationDidFinishLaunching,
the global side effect KanbanApp.init must not carry. The board toolbar
gains its first .picker item — an NSMenuToolbarItem whose rows re-fetch
their spec fresh, checkmark read at menu-open like every other menu row —
and Appearance joins the search field as the second default item,
centered beside it (03-board-ui.md ▸ Toolbar, ratified 2026-08-07).

// MARK: - The board window's toolbar
/// The board window's toolbar (03-board-ui.md ▸ Toolbar).
///
/// ### The default is the search field and Appearance, and the catalog is the rest
///
/// "**Board window default: the search field and Appearance** — both **centered**, the titlebar's
/// view-controls cluster." The flexible space ahead of the pair is what keeps them off the leading
/// edge before `centeredItemIdentifiers` takes over their placement.
///
/// "**Catalog** (available via Customize): New Card, New Lane, Zoom In, Zoom Out …, Undo, Redo …,
/// Show Trash (toggle state matching the View menu checkmark)." Every one of them is the *same command* as its menu row
/// — the predicates below are the rows' own (`BoardStore.newCardTarget`, `acceptsBoardMutations`),
/// and the two actions with consequences call the rows' own functions (`beginNewCard`,
/// `setTrashVisible`) rather than restating them. That is what makes "toolbars are pure enhancement"
/// true of the code: removing every item removes nothing but a shortcut to a menu row.
///
/// "The board popover deliberately has **no toolbar item** — the window-title widget is its
/// committed home" — so there is no Board Info entry here, and its absence is pinned by a test.
///
/// ### Undo and Redo are the responder chain's, exactly as the menu's are
///
/// The app ships no Undo/Redo rows of its own: those are the standard Edit-menu items, nil-target
/// `undo:`/`redo:` resolved up the responder chain (`KanbanApp.menuCommands`). The toolbar items
/// carry the same actions with the same nil target, so "matching their menu items" (03) is not a
/// predicate written here — it is literally the same validation. Both reach the board window, whose
/// `windowWillReturnUndoManager` hands back the session's `BoardUndoManager`, and both therefore
/// enable exactly when that board has a step to cross and no read-only lock stands
/// (13-native-undo.md ▸ Rules). **Every board has undo in every tier**, so there is no tier-shaped
/// disablement to write: 03's parenthetical about boards without undo is 06's *git* substrate, which
/// only a Pro subscription binds.
///
/// Their labels are the design's one exception to the menu-title rule: `NSUndoManager` rewrites the
/// *menu* titles as the stack changes ("Undo Move Card"), which a toolbar label does not track, so
/// these two are built from static labels (`ToolbarItemSpec.staticLabel`).

/// `UserDefaults` at build time, since `WindowToolbarController.trackValidationState` re-arms
/// observation over each spec's `isEnabled` and a plain scalar would leave Zoom In looking live
/// at the top rung.
/// - appearance: the app-wide appearance override, `zoom`'s reason exactly — not the store's,
