Parse completedAt/certificate/result from Verae API; enrich merkle via
POST /api/verify (blockIndex). Generate certificate with the same jsPDF
layout as register.html export. Preserve original filename (e.g. .html).
Match the official Verae Timestamp Registration Document layout (logo,
frames, field list, QR). Disclaimer: only the digest was submitted.
Lookup/footer use explorer.verae.ai — no mcp.verae.ai or “via MCP”.
