Summary

Production index.html now bakes absolute https://dex.cl8y.com/og-image.png for og:image / twitter:image (X/Twitter drops relative paths). Origin is allowlisted in viteOg.ts and never taken from the request host header, query, or wallet/pair.
Replaced the #488 product-copy card with a 1200×630 community-medallion PNG (~661 KB) recomposed from the square source (not stretched). Concept lives in frontend-dapp/brand/ so crawlers keep using /og-image.png.
Documented invariants OG-1–OG-8, added skills/AGENTS_FRONTEND_OPENGRAPH.md, and make verify-issue-578 (no LocalTerra).

Closes #578

Test plan

make verify-issue-578 (run twice; also after rebase) — F1–F3, A1–A7 greps/tests
og-image.png is 1200×630 PNG under 1 MB
nginx location = /og-image.png serves a real image; SPA routes still fall back to index.html
After Coolify deploy: curl -sL https://dex.cl8y.com/ | grep og:image shows the absolute URL
curl -sI https://dex.cl8y.com/og-image.png → 200 image/png
Telegram + X/Twitter (reset card cache) + Discord large preview of https://dex.cl8y.com

Acceptance criteria

AC1 — Production bake uses absolute https://dex.cl8y.com/og-image.png (Vite og-absolute-meta; Coolify VITE_PUBLIC_ORIGIN default)
AC2 — twitter:card is summary_large_image; title/description unchanged in spirit; no invented twitter:site
AC3 — /og-image.png is 1200×630 community-medallion composition, ~661 KB (hard max 5 MB)
AC4 — nginx still rewrites SPA routes to the same index.html (same static meta). Live curl of prod routes is post-deploy.
AC5 — og:image:width / height / alt (and twitter:image:alt) present and match the file
AC6 — OG origin allowlist rejects http:, javascript:, data:, protocol-relative, credentials, query, and unknown hosts. No SVG OG. No new CSP image hosts.
AC7 — Design-system, AGENTS skill, #488 QA note updated. Concept committed as source; crawlers use /og-image.png.
AC8 — Manual Telegram and X/Twitter (and Discord) after deploy + crawler refresh

Closes #578

## Summary - Production `index.html` now bakes absolute `https://dex.cl8y.com/og-image.png` for `og:image` / `twitter:image` (X/Twitter drops relative paths). Origin is allowlisted in `viteOg.ts` and never taken from the request host header, query, or wallet/pair. - Replaced the #488 product-copy card with a 1200×630 community-medallion PNG (~661 KB) recomposed from the square source (not stretched). Concept lives in `frontend-dapp/brand/` so crawlers keep using `/og-image.png`. - Documented invariants **OG-1–OG-8**, added `skills/AGENTS_FRONTEND_OPENGRAPH.md`, and `make verify-issue-578` (no LocalTerra).
