PR Summary

Low Risk
Low risk: adds client-side analytics capture calls on landing-page interactions without changing business logic or server APIs.

Overview
Adds PostHog tracking across the landing page for key conversion actions.

Introduces a typed trackLandingCta helper and wires landing_cta_clicked into hero, navbar (desktop + mobile), pricing, and footer CTAs; also captures landing_prompt_submitted when users submit prompts from landing inputs and landing_demo_request_submitted after a successful demo request (including company_size).

Extends the PostHog event catalog (PostHogEventMap) with these new landing events to enforce property shapes at capture sites.

Greptile Summary

This PR adds PostHog analytics tracking across the Sim landing page, covering three categories of user interaction: CTA button clicks (landing_cta_clicked), demo form submissions (landing_demo_request_submitted), and prompt submissions from any of the three landing-page input areas (landing_prompt_submitted).

Key changes:

• Three new strongly-typed events added to PostHogEventMap in events.ts, maintaining the compile-time safety contract shared by all call sites
• A trackLandingCta helper exported from landing-analytics.tsx provides a single, consistent entry point for all CTA tracking — used across hero, navbar, footer, and pricing components
• captureClientEvent is called directly for landing_prompt_submitted in the three prompt-input components, which is appropriate since no equivalent wrapper was added for that event
• The demo modal captures company_size from the Zod-validated payload on successful HTTP submission only, so the event is never fired on validation failure or network error
• All components that import trackLandingCta from landing-analytics.tsx (which carries 'use client') are themselves client components, so the import chain is valid

The implementation is clean and consistent with existing PostHog patterns in the codebase. No issues found.

Confidence Score: 5/5

This PR is safe to merge — it adds purely additive analytics tracking with no logic changes to existing functionality.

All 9 changed files pass review with no bugs, logic errors, or rule violations. Events are properly typed, call sites are correct, and the trackLandingCta abstraction is a clean, consistent pattern. No P0 or P1 findings.

No files require special attention.
