Subject: [PATCH] Add favicon: square-framed stampstack 3D mark (app/icon.svg)

Next.js App Router auto-serves app/icon.svg and injects the <link rel=icon>.
The portrait brand logo is reframed to a square viewBox (centered, padded) so it
renders undistorted at favicon size; artwork/paths untouched.

+<!-- Favicon: the stampstack 3D mark. Next.js App Router auto-serves app/icon.svg
+     and injects the <link rel="icon"> tags. The artwork is the brand logo, kept
+     intact; only the outer <svg> is reframed to a square viewBox (centered on the
+     art, with padding) so the tall portrait mark renders square without the
+     stretch that preserveAspectRatio="none" would cause. Fill falls back to the
+     brand blue when the CSS var isn't defined (i.e. everywhere outside the app). -->
