+      Favicon is inlined as a data: URI rather than a /favicon.svg file because
+      the daemon's static server only exposes /assets/* and / (see
+      packages/cli/src/serve/web-shell-static.ts) — a file at the dist root
+      would never be reachable. The data: URI is allowed by the shell CSP
+      (img-src 'self' data: blob:). The encodeURIComponent(svg) encoding
+      technique mirrors packages/web-templates/src/export-html/build.mjs;
+      the artwork is from packages/desktop/apps/webui/src/public/favicon.svg
+      (the purple #6D44E8 Qwen mark, legible on both light and dark browser
+      tab bars).
