“Paid in Full”是使用 FontVibe AI 创作的复古文字效果。衬线大写字母凸版压印进米色棉卡纸，墨色略有破损，放在旧印刷机台面上，周围散落金属活字。

Create a finished, horizontal 3:2 stamp design for an invoice pad, shown as a clear ink impression on aged cream cotton paper. Render exactly this text, with no additional words: “Paid in Full”. Make it the single headline, centered and immediately legible, in flowing fountain-pen handwriting inspired by copperplate: connected letterforms, expressive thick downstrokes, fine but sturdy upstrokes, natural slight baseline variation and subtle ink pooling at stroke endings. Keep the fine strokes strong enough to remain readable at invoice-stamp size. Surround the phrase with a thin, softly irregular double-line rectangular frame and restrained small corner flourishes. Use warm faded sepia ink with slight pressure variation, tiny broken patches and lightly worn edges to suggest a real rubber stamp transfer; the lettering remains clearly readable. Show paper grain, faint foxing and soft amber illumination, with the stamp mark as the central focus and generous clear margins. Restrict the palette to aged cream, warm tan and sepia. No hands, no visible stamp tool, no extra lettering, no logos, no mockup shadows obscuring the impression.
