Description

Users might upload the site logo to their site in .ico format; this doesn't load in the emails via our CDN.

Working file path: `mimarsozluk.com.tr/wp-content/uploads/2024/01/favicon.ico`

Non working CDN path: `i0.wp.com/mimarsozluk.com.tr/wp-content/uploads/2024/01/favicon.ico`

Results in:

![image](https://github.com/user-attachments/assets/1b674b57-f0ec-4808-a521-4db5df9ed73f)

Solution ideas:

- Skip CDN for .ico?
- Resolve to default logo when detecting non-supported file format
- Support .ico at our CDN

Research direction

Reproduce the failure using the working and non-working URLs in the report, then locate the newsletter image and CDN handling entry point for .ico assets. Confirm the intended behavior with maintainers—bypass the CDN, use a default logo, or add CDN support—and verify that .ico logos load in email output.
