+  <!-- DeepCode logo, macOS icon grid: white cat on brand-blue squircle.
+       The squircle is inset to ~80% of the canvas with a transparent margin
+       (macOS Big Sur+ grid: 824/1024 ≈ 80%, corner radius ≈ 22.5% of the
+       square), so the icon sits the same visual size as its Dock neighbours
+       instead of bleeding edge-to-edge. The cat is inset inside the squircle
+       so it reads as a mark, not a full-bleed silhouette. -->
