Move examples/*.sx and their expected/ snapshots into per-category subfolders (examples/<category>/...). Folder = leading filename token, with ffi-objc/ffi-jni kept whole; filenames are unchanged. The corpus runner and LSP sweep now discover each category's expected/ dir, while issues/ stays flat. Example 1058's repo-root-relative companion import is made file-relative. Path strings embedded in 164 snapshots were regenerated (path-only changes). Test-layout docs in CLAUDE.md updated.

// Show something on screen — a UIWindow with a colored UIViewController root.
|
||
//
|
||
// Builds on 5.7's AppDelegate. Inside `didFinishLaunching`, we:
|
||
// 1. [[UIWindow alloc] initWithFrame:CGRect]
|
||
// 2. [[UIViewController alloc] init]; set view.backgroundColor
|
||
// 3. window.rootViewController = vc
|
||
// 4. [window makeKeyAndVisible]
|
||
//
|
||
// We hardcode the frame to 1024×1024 to avoid the struct-return ABI of
|
||
// `[UIScreen mainScreen].bounds` for now — any frame bigger than the device
|
||
// covers the screen, modulo safe-area insets.
|
||
//
|
||
// `g_window` is a module-level global so the window outlives the IMP scope
|
||
// (no ARC; UIKit retains it as the key window anyway).
