+------------------------------------------------------------------------------
+Modifications in this fork (per Apache License, Version 2.0, Section 4(b)):
+
+  - Image: an optional real `src` now renders an actual <img> element
+    (object-cover), with a placeholder fallback when absent.
+  - Pressable: a clickable container that wraps arbitrary children and emits
+    a `press` event.
+  - Lightbox: a self-contained photo gallery (thumbnail grid + fullscreen
+    overlay with prev/next and keyboard/backdrop close) that manages its own
+    state.
+  - Modal: a self-contained modal whose trigger button and popup are a single
+    component, managing its own state.
+  - Playground: generation routed through the OpenAI-compatible ai.mm.mk
+    gateway.
+
+  Primary changed files:
+    apps/web/lib/render/registry.tsx
