Don’t forget your booking

We were discussing how the favicon should report the status of a deployment pipeline, and I showed my team the following example from

Once you land on the Booking page of the website, the title says “Your Details”

If you leave the tab, it changes to “Don’t forget your booking”
And if you wait longer, it turns into yellow and adds (1) to signal something like a notification

This is master persuasion. Even the smallest thing like the favicon and tab title can have a big impact.
