When would server side rendering be the better choice over static site generation or incremental static regeneration?

Server side rendering is the right choice when a page's content must be completely up to date on every single visit and cannot tolerate any staleness, such as a live stock ticker, a personalized dashboard showing a specific user's private data, or a page whose content depends heavily on cookies or request headers.

// Using cache: 'no-store' forces server side rendering behavior
const res = await fetch('https://api.example.com/stock-price', { cache: 'no-store' });
