Integrates PostHog JS SDK for cookieless analytics and adds an e2e test verifying initialization.
Changes
src/main.ts:posthog.init()call beforecreateAppwith cookieless mode, EU API host, and bot detection / batching disabled in dev/testtests/e2e/posthog.spec.ts: Playwright test intercepts requests toeu*.i.posthog.comviapage.route, fulfills with200 {}, and asserts ≥1 request fires on page loadpackage.json: Addedposthog-jsdependencyTesting PostHog init in Playwright — approaches tried
/decideendpoint/decidewith/flags/and/configpage.evaluate(() => window.posthog)windoweu*.i.posthog.comeu.i.posthog.comandeu-assets.i.posthog.comThe chosen approach (network interception) is the most robust: it doesn't depend on specific PostHog internal endpoints or global variable exposure, and mocking the responses means the test doesn't require external connectivity.
