 - **A new image suite gets a target, not a scheme.** Add the `*SnapshotTests` target. List only `SnapshotKitTesting` in `extraPackageProducts`. Add it to the `StuffSnapshotTests` scheme's build and test lists. Never add a scheme or CI job of its own. An image bundle links only what its module needs (the Periscope and Inspector suites don't build against WhereUI at all). References follow the sources automatically via `#filePath`.
 - **Generated websites use the same snapshot scheme.** `ToolsSnapshotTests` renders the install site's production Astro HTML in hosted WebKit through `SnapshotKitTesting`. Its fixture generator runs during each bundle build and needs the installed site dependencies; see [`Tools/AGENTS.md`](Tools/AGENTS.md#install-site-snapshots).
 - **Separate snapshot bundles are safe because each `.xctest` gets its own `StuffTestHost` process** (measured on Xcode 27 — `ProcessInfo.processIdentifier` probes. Details in the snapshot-bundle comment in [`Project.swift`](Project.swift)). Each bundle statically embeds its own copy of `SnapshotKitTesting`'s capture state. Two copies in one process corrupt each other. Tripwire: if a toolchain ever shares one host process across bundles, re-measure before adding another image bundle.
-- **Snapshots containing scrolling content use full-content sizing.** Use SnapshotKit's full-content device presets for ordinary `ScrollView`, `List`, `Form`, or equivalent UIKit-backed content. Those presets keep the normal device width and minimum viewport height while growing vertically. Use an explicit two-axis preset for a spatial canvas that intentionally scrolls in both dimensions. Its bounded capture grows from the normal viewport along both axes. Fixed device frames are for subjects without scrolling content. Preserve production navigation, tab, sheet, search, and toolbar chrome when measurement converges. Snapshot an intentionally bounded or greedy container's shared scrolling child directly. Never add snapshot-only production layout (see `SnapshotConfiguration.Frame.fullContent` and `.fullContent2D`).
