Hearing whispers about budget cuts affecting my division...

Been with Amazon for about 4 years now, mostly on the retail tech side, specific team is something like 'customer experience personalization'. Lately, there's been a lot of buzz around budget reviews and 'optimization efforts'. My manager is being super cagey, just saying 'things are under review'. We had a mandatory all-hands where the director talked a lot about 'fiscal responsibility' and 'streamlining operations'. It felt like code for something, you know? No one's explicitly said layoffs, but the vibe is definitely shifting. Anyone else in similar divisions hearing similar things? Trying to gauge if this is a company-wide thing or just our specific corner of the org.
