 - `jsray-mark-*.svg / .png` — standalone icon (app icon / favicon), 160×160 rounded square
-- `jsray-logo-*.svg / .png` — icon + JSRay wordmark, horizontal lockup (**designer source, 760×240 — do not edit**)
-- `jsray-logo-hero-*.svg` — README/web display derivatives of the lockup: transparent
-  background, ink centered on the same 760×240 canvas (viewBox translated only —
-  identical geometry and rendered scale). Regenerate from the originals if the
-  lockup design changes.
+- `jsray-logo-hero-*.svg / .png` — icon + JSRay wordmark, horizontal lockup:
+  transparent background, ink centered on a 760×240 canvas. `-dark` carries
+  white ink for dark surfaces, `-light` near-black for light ones. The PNG is
+  rendered from the SVG at 1520×480 and exists because a VS Code Marketplace
+  README cannot reference SVG.
 - `-dark` = dark-background version (dark surfaces / dark UI)
 - `-light` = light-background version (light surfaces / print)
