The configuration option 'defaults' with value '2025-11-30' appears to be invalid. PostHog's init method does not have a 'defaults' configuration option documented in their API. This may have been intended to be 'person_profiles' or another valid configuration option. Additionally, the date '2025-11-30' is in the past (current date is February 2026), which suggests this may be a placeholder or incorrect value. Please verify the intended configuration option and its correct value.

PostHog initialization should be conditional based on environment, similar to how Sentry is initialized only when the saas flag is true (lines 73-85). Currently, PostHog will initialize in all environments including local development, which may not be desired and could lead to test/development data being sent to PostHog.

The PostHog API key is hardcoded directly in the source code. This is a security concern as the key will be visible in version control history and to anyone with access to the repository. Consider moving this to environment configuration files or a secure configuration service, following the same pattern used for Stripe keys (lines 64-67) or Sentry DSN (line 75).
