Do not merge until Business Heartbeats QA passes; merge is left to the parent agent.

• New route /features/missing-event-alerts (new /features section; no conflict with draft feat(marketing): gated Next.js monitoring draft for Oct 25 review #765, which only adds /monitoring/nextjs).
• Title, H1, meta description, structure, 6 FAQs (FAQPage JSON-LD via faqPageJsonLd in lib/marketing-guide-metadata.ts), CTA, internal links per brief; we/our voice.
• Claims limited to v1.22.10: one named event per condition, 1–24 h window, optional environment filter. Channels (code-verified, shared ALERT_RULE path): email (default), in-app notifications, HTTPS webhooks, Slack, Discord, Microsoft Teams, Telegram. Setup steps not duplicated; links to /docs/alerts and /docs/checkins. States no recovery notification, ~5 min scheduled checks (not real-time), user-sent events, no guarantees. No plan limits.
• Added to sitemap (PUBLIC_SEO_PATHS + MARKETING_GUIDE_PATHS, lastmod bumped) and llms.txt; /docs/alerts heartbeat section gets an id anchor and a link to the page.
• GuideCta: optional primaryLabel prop (default unchanged "Start free") for the "Add your first heartbeat" CTA.
• Tests updated; dashboard vitest, lint, build pass locally.
