v2026.2.16

What changed

• Improved social preview reliability for promo links (including Farcaster/Warpcast):
  • default OG fallback image is now raster PNG (/og.png) instead of SVG
  • promo page now emits richer OG/Twitter image metadata (og:image:secure_url, type, dimensions, alt)
  • app now trusts proxy headers for canonical HTTPS metadata behind tunnels/proxies
  • promo route (GET /) now returns 200 even after sale end so crawlers can still build previews
• Added HEAD support for OG image endpoints:
  • /og.png
  • /og.svg
  • /og-image
• Unpaid browser handling for GET /download (402) now renders leak’s custom guidance page while preserving x402 protocol headers (PAYMENT-REQUIRED) and existing API behavior.
• Unified root promo page and unpaid /download guidance content so both show the same details block:
  • price/network/sale end
  • Agent Quick Path
  • human action copy-link control
  • install note

Breaking changes

• None.

Skill updates
