rzen ca5d45156b A picture off the pasteboard becomes a card's file, its hero, or the board's backdrop
⌘V grows an image-data branch, below the app's own clipboard format and refused
outright while a file URL is on the pasteboard: a screenshot or a browser's Copy
Image lands as "Pasted Image.png" in the anchor card's attachments/, through the
very import path Finder file drops and ⇧⌘A take — one bracket, one Finder-style
collision ladder, one set of banners, and the same silence a drop's arrival has.
A card window's ⌘V pastes onto its own card; a focused text field still wins the
selector natively. A file-shaped flavor travels byte for byte, PNG preferred when
several are offered; TIFF and BMP are re-encoded to PNG, being interchange
encodings rather than files anyone wants in a folder.

The hero key gets the setter it was born owing: "Set as Hero" on any image row of
the attachment list, "Remove Hero" on the row that holds it, with menu-bar twins
so the context entry is nobody's only home. It writes as a restyle — one key, one
bracket, one invertible step on the window's own stack — and replaces rather than
refusing, because a card has one hero and the row that has it says Remove instead.

Edit ▸ Paste as Board Background is the same payload's other destination, taking
the existing background.image convention at its word: the picture into the board
folder as "Pasted Background.png", the colour subkey untouched, the generator's
overwrite-our-own-name rule inherited and its echo memo taught to tell the two
producers apart.

/// The scene graph (02-architecture.md § Windows, § Launch and window lifecycle).
///
/// ### Four scenes, and why each is the kind it is
///
/// - **Welcome** is a `Window`: there is one of it, ever, and `openWindow(id:)` focuses the existing
/// one rather than making a second.
/// - **The restore bootstrap** is a `Window` too, and a deliberate oddity — see
/// `RestoreBootstrapView` for why launch-time work has to wear a window at all.
/// - **Boards** and **cards** are `WindowGroup(for:)`s, because their identity is a *value*: opening
/// with a ref that already has a window focuses it, which is how "one board window per root" and
/// "at most one card window per card (reopen focuses)" are enforced by the scene rather than by
/// bookkeeping.
///
/// ### Restoration is the registry's, not the system's
///
/// Both groups declare `.restorationBehavior(.disabled)`. The app already knows which boards were
/// open — the registry's open-now flags, which survive a crash and reopen in `lastOpened` order —
/// and letting AppKit *also* restore windows would produce duplicates, and worse, card windows
/// restored behind boards that never opened. One mechanism, and it is the one that can explain
/// itself when a board has moved or gone.
///
/// ### Which window appears at launch
///
/// Exactly one of welcome and the bootstrap, decided once in `init` and never re-derived (see
/// `LaunchPlan`): the preference is read before any scene exists, and `restorables()` costs a
/// bookmark resolution per known board — a computed property here would pay that on every
/// scene-graph evaluation.
