Create a vertical vintage religious icon-style portrait card of an elderly male saint or philosopher, painted like a Renaissance devotional illustration on aged parchment. The central figure has short gray hair and a partial gray beard, with his face deliberately covered by a flat opaque tan rectangle, standing before a radiant golden halo with sunburst rays against a soft blue sky with clouds. He wears a cream tunic with gold trim and a deep blue draped robe, raises his left hand with one finger pointing upward, and holds a curled parchment scroll in his right arm. The scroll contains a centered serif quote in 5 visible lines: “Good ideas aren't validated by opinions. They're validated by customers willing to pay.” with a small ornamental divider beneath. At the bottom, include a cream nameplate with large spaced serif capitals reading “STEVE BLANK”. Frame the image with an ornate gold rectangular border, scalloped cream outer edge, and exactly 4 decorative floral corner clusters: top-left, top-right, bottom-left, and bottom-right, each with roses, white lilies, green leaves, and gold filigree. Use warm muted colors, aged paper grain, hand-painted brush texture, devotional holy-card composition, soft glow, symmetrical layout, and elegant antique typography.
