#15581 Rework landing story and refresh Integrate page

Landing

• After the hero, usage graphic and Stilla story, the page runs the numbered story chapters: 01 Meter, 02 Charge, 03 Understand, 04 Sell globally, 05 Agents. Primitives and Platform are off the page.
• Figures use the window-and-sheet frame over the flow images (shared WindowFrame in story/Frame.tsx).
• Sell globally is an animated order that moves through payment, fraud, tax and payout across Berlin, London, Austin and Tokyo.
• Meter: graphic cards with Learn more links, and the ingestion window opens with a blinking cursor.
• Testimonials below the lead quote are cards. The hero has a Get Started button.

Integrate

• Figures sit in the shared window frame on dimmed, rounded photos. Cards are rounded and chapters are numbered (01 MCP to 04 API).
• Hero: a looping Claude Code session over the Polar MCP server that rotates through four prompts.
• MCP chapter reuses the landing Agents figure, opening with "Integrate Polar for billing in my stack".
• CLI chapter is one terminal window (install, webhook listen, webhook trigger, auth whoami --json), checked against the CLI source.
• SDK examples pin API version 2026-10, matching the docs.

Notes

• Demo copy in the figures (agent answers, prices, payouts) is illustrative.
• Lint, format and typecheck pass. Landing tests pass.
