Multi-language snippets

One example, several languages, using fd-tabs.

When a doc serves readers across languages or tools, put the variants in <fd-tabs> instead of stacking code blocks:

const response = await fetch('/api/rates', { method: 'GET' });

var response = await httpClient.GetAsync("/api/rates");

curl -s https://example.test/api/rates

The reader picks once and stays oriented; the page stays short.
