Should mobile and desktop share one timeout?

Timeout is how long the auction waits for bids. It's tempting to set one number for everyone, but phones and desktops aren't equal.

— Same timeout everywhere: simple, but phones on slow networks often can't answer in time, so mobile loses bids.
— Split timeouts: give mobile a longer wait (say 1500ms) and desktop a shorter one (1000ms), matching their real speed.

Tiny example: a desktop bidder replies in 400ms; the same bidder on 4G takes 900ms. One tight timeout quietly cuts off your mobile money.

1. Measure bid response time by device.
2. Set each device its own timeout.

In plain English: phones are slower, so give mobile a longer wait than desktop.
