Subject: [PATCH] docker: forward NEXT_PUBLIC_POSTHOG_TOKEN into the build
 stage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Docker silently drops --build-arg values without a matching ARG
declaration, so the PostHog token never reached next build and was
never inlined into the client bundles — posthog.init() guard stayed
undefined in prod.
