Sync Chrome.tsx wordmark <img> intrinsic dimensions to 411×110 (match Close.tsx and SVG source) #50

Background

The canonical wordmark asset public/wordmark-light.svg declares its authored intrinsic dimensions as:

<svg width="411" height="110" viewBox="0 30 411 110" ...>

After #47, components/site/Close.tsx:26-27 declares the matching attrs on its <img>:

<img src="/wordmark-light.svg" ... width={411} height={110} ... />

The two <img> instances in components/site/Chrome.tsx still carry the older smaller dimensions:

• components/site/Chrome.tsx:136-137 (light variant): width={112} height={30}
• components/site/Chrome.tsx:144-145 (dark variant): width={112} height={30}

Issue

112 / 30 ≈ 3.7333, while the SVG's authored ratio 411 / 110 ≈ 3.7364. The drift is ~0.08% — visually invisible, no CLS regression — but it's the same canonical asset declared in two call sites with different numbers, and one of them no longer matches the source.

The HTML width / height attrs only feed the browser's aspect-ratio reservation; CSS still controls rendered size in both files (the navbar wordmark renders at ~112×30 regardless). So this is purely a convention/consistency cleanup.

Surfaced by a code-reviewer pass on #47 (#47).

Proposed change

Update both <img> blocks in Chrome.tsx to use the SVG's authored dimensions:

   <img
     src="/wordmark-light.svg"
     alt="decdn"
-    width={112}
-    height={30}
+    width={411}
+    height={110}
     className={onDark ? "hidden" : "block"}
   />
   <img
     src="/wordmark-dark.svg"
     alt="decdn"
-    width={112}
-    height={30}
+    width={411}
+    height={110}
     className={onDark ? "block" : "hidden"}
   />

The rendered navbar size is unchanged because no CSS is touching width/height on those elements — the browser would already compute width from the resource's intrinsic dimensions; the attrs were just providing a (slightly off) hint for the CLS reservation. After the change, both call sites declare the wordmark's real authored dimensions verbatim.

Verification

• pnpm build succeeds (static export).
• Navbar wordmark renders identically (same pixel size in both light and dark mode toggles).
• DOM inspector confirms width="411" height="110" on both navbar variants.
