Add Favicon URLs

Internal Service — This is not an HTTP endpoint. It’s called by the competitor research service.

Purpose

Adds favicon URLs to each competitor using Google’s favicon service. Filters out generic globe icons.

async def add_favicon_urls_to_competitors(competitors: list) -> None

Parameter	Type	Description

https://www.google.com/s2/favicons?domain={domain}&sz=64

Google returns a generic globe icon for domains without favicons. We detect this by comparing MD5 hashes:

GOOGLE_GENERIC_GLOBE_HASH = "b8a0bf372c762e966cc99ede8682bc71"
