Favicons
Action required before deploy: copy your existing favicon set from the current blog here.
From your old Chirpy-based site, copy these files from assets/img/favicons/ into this directory:
favicon.ico
favicon-16x16.png
favicon-32x32.png
apple-touch-icon.png
android-chrome-192x192.png
android-chrome-512x512.png
mstile-150x150.png
site.webmanifest
browserconfig.xml
_includes/head.html already references them. Until you add them, browsers will 404 the favicon (harmless, but visible in the network tab).
