Closes mc#1486.

Summary

Adds the standard Next.js App-Router SEO surface to the canvas landing so the marketing push has crawlable metadata + structured data on day one. Per-issue scope is metadata/OG/sitemap/robots/JSON-LD only — no design or copy changes.

What landed

• canvas/src/app/layout.tsx — Metadata API (title.template, description, keywords, canonical, metadataBase, OG/Twitter text fields, robots index:true) + JSON-LD @graph of Organization + WebSite + SoftwareApplication injected via the existing per-request CSP nonce.
• canvas/src/app/robots.ts — allow /, /pricing, /blog; disallow /orgs, /api/, /cp/, /checkout/; declares sitemap URL + canonical host.
• canvas/src/app/sitemap.ts — apex, pricing, live blog post; authed routes excluded.
• canvas/src/app/opengraph-image.tsx — segment-level dynamic OG card (1200x630) via next/og ImageResponse; no static binary blob.
• canvas/src/app/__tests__/seo-routes.test.ts — 10 vitest cases pinning the crawler contract (robots allow/disallow, sitemap presence, OG/Twitter text, canonical, index:true).

Out of scope (per the issue)

• Hero rewrite, design changes, copy. Those are CTO/marketing inputs.
• Lighthouse CWV tuning (LCP image priority etc.) — needs a deployed preview to measure against; will be a follow-up ticket once the marketing copy lands.

Diff size

422 lines / 5 files. Layout edits are net +140 (metadata block + JSON-LD); the other four files are new.

Test plan

• npx vitest run src/app/__tests__/seo-routes.test.ts → 10/10 pass locally.
• npx tsc --noEmit on the new files: clean (pre-existing repo-wide TS errors in unrelated test files are not regressed).
• CI must pass before merge — do NOT admin-merge bypass.
• Post-merge: verify /robots.txt and /sitemap.xml resolve on the staging deploy; capture Lighthouse SEO score on the deployed preview and attach as a follow-up comment (target: ≥ 95).
• Validate the OG card preview in https://www.opengraph.xyz/ once the staging host is live.

Notes

• metadataBase honours NEXT_PUBLIC_SITE_URL and falls back to https://app.moleculesai.app so previews on Vercel/Railway pick up the right canonical host.
• The JSON-LD includes AggregateOffer pointing at /pricing (low: $0, high: $99) so rich-result eligibility is wired from launch.
• Tenant subdomains share this build; AuthGate redirects anonymous traffic to the CP login, and per-host noindex is enforced separately at the middleware layer.

feat(canvas): homepage SEO for marketing launch (mc#1486) ... 82a6cf42cd

Adds the standard Next.js App-Router SEO surface to the canvas
landing so the marketing push has crawlable metadata + structured
data on day one.

What landed:
  - layout.tsx — Metadata API: title.template, description,
    keywords, canonical, metadataBase, OG/Twitter text fields,
    robots index:true. JSON-LD @graph (Organization + WebSite +
    SoftwareApplication) injected with the per-request CSP nonce.
  - robots.ts — allow public marketing routes (/, /pricing, /blog),
    disallow /orgs, /api/, /cp/, /checkout/; declares sitemap +
    canonical host.
  - sitemap.ts — apex + pricing + live blog post; authed routes
    excluded by construction.
  - opengraph-image.tsx — segment-level dynamic OG card via
    next/og ImageResponse (1200x630); no static binary blob.
  - __tests__/seo-routes.test.ts — pins the crawler contract
    (10 cases) so a future refactor can't silently flip the
    marketing surface to noindex or drop the sitemap.

Out of scope (per issue): design copy, hero rewrite, Lighthouse
CWV tuning. Those are CTO/marketing inputs and a separate ticket.

1. Correctness — diff matches stated intent; no obvious logic regression.
2. Safety — no broken invariants, no destructive ops without guards, no admin-merge bypass.
3. Tests — assertions match the bug class; no tautologies.
4. Surface — no secrets in diff; trust boundary unchanged.
5. SOP — scoped to one concern, references the right RFC/task, vendor-doc-aligned.
