I've created a branch droid/issue-14 with the favicon implementation:

Changes

• Created an SVG favicon (docs/favicon.svg) with a feed-style icon
• Added favicon link to docs/index.html and docs/stats.html

The favicon design:

• Black background with rounded corners
• Three horizontal lines representing feed items
• A circular accent in the corner representing notifications/updates
• Works well in both light and dark browser themes
