@@ -9,10 +9,13 @@ Each scene is captured at **40×12** (narrow) and **120×40** (wide), twice:
 - `40x12/`, `120x40/` — raw terminal pixels. The background is the host
   terminal's (`Color::Reset`, black by default); nothing paints a navy wash
   and no rounded frame is drawn — the TUI bleeds to the terminal edges.
-- `macos/40x12/`, `macos/120x40/` — the same captures composited 1:1 into a
-  macOS Terminal.app window (traffic lights, `cortex-api — cortex — W×H`
-  title, native shadow) on a desktop wallpaper. The rounded corners belong
-  to the macOS window chrome only, never to the TUI.
+- `macos/40x12/`, `macos/120x40/` — the same captures composited into the
+  designer macOS chrome template: Sequoia ray wallpaper, menu bar, and a
+  Terminal.app window (traffic lights, `cortex-api — cortex — W×H` proxy
+  title, native shadow). The 120×40 captures scale into the window's black
+  content rect; the 40×12 captures keep the same chrome with a smaller
+  content rect. TUI pixels are only ever scaled uniformly — never re-typed —
+  and the rounded corners belong to the macOS window chrome only.
 
 Chrome rules: `#A78BFA` violet for the `>` prompt, selection caret, `●` tile
 dots and `✓` checks; selected rows are light text on the dark `#221A38` bar
