129-132: Environment-gate the GA tracking config.

gtag is unconditionally enabled with a hardcoded production Measurement ID. Environment-gate it to prevent analytics pollution from non-production deployments. Verify separately that consent handling is implemented (code search did not locate explicit consent patterns).

In `@docusaurus.config.ts` around lines 129 - 132, The gtag block is
unconditionally set with a hardcoded Measurement ID; change it to only include
gtag when running in production and when an env var provides the ID. Replace the
static gtag object (trackingID: 'G-5EY968JNZT', anonymizeIP: true) with code
that reads process.env.GA_MEASUREMENT_ID (or similar) and process.env.NODE_ENV
=== 'production' and only assigns the gtag property when both conditions are met
(preserve anonymizeIP), otherwise omit or set gtag to undefined; update any
config typing to accept an optional gtag to avoid compile errors.
