Safari < 26.0 doesn't support svg favicon and even after 26.0, it
defaults to #000 color, resulting to black favicon on white background.
It is better to have actual ico image hosted on /favicon.ico
To prevent chrome and other browsers choosing ico image for favicon over
svg, we are restricting the favicon.ico size to 48x48.
180x180 apple-touch-icon.png is also needed to support Safari bookmark
icons. Commonly known as "Favorites". Because Safari bookmark icons is
pretty large, we are using logo-dolly (dolly with eyes) here.
