Minimal SaaS Ad With Invoice Mockup

Create a minimalist static SaaS ad with a warm off-white background, elegant typography, and crisp, high-fidelity text rendering. Place a large, two-line black serif headline at the top that reads:{argument name="headline text" default="Your dev team shouldn’t be your analytics team."} The word "dev team" should be in italic serif font, while the rest should be in bold, high-contrast serif font with ample white space and a luxurious magazine-style layout. Below, centered, is a slightly tilted white paper invoice with a soft shadow and a subtle vertical crease in the middle, as if photographed from above. The invoice uses black, monospaced typewriter-style text, clearly stating the title: "INVOICE — DEV HOURS, OCTOBER," followed by five lines of aligned work hours and pricing details: "A/B test setup on pricing page 8 hrs $1,200", "GTM tag install (3 events) 4 hrs $600", "Funnel tracking debug 6 hrs $900", "Meta pixel mapping 3 hrs $450", and "Attribution reporting build 12 hrs $1,800". Add a dotted line separator below each item, and write "TOTAL" in bold, equal-width text in the lower left corner, and the total price "$4,950" in the lower right corner. Cross out the total price with a hand-drawn yellow line. Add four doodle-style annotation elements around the invoice: on the left, handwritten yellow text "every month??" with a yellow arrow pointing to the paper; a yellow star doodle in the upper right corner of the paper; a green curved arrow pointing to the crossed-out price below the total price; and a green hand-drawn circle in the lower right corner containing the handwritten text "zero devs," connected to the green arrow. At the bottom center of the advertisement, add two lines of smaller black sans-serif text:{argument name="body text" default="Marketers ship tests and track revenue themselves.\nNo tickets. No tag manager. One script."} "Maintaining a transparent, sophisticated, and conversion-oriented composition, it integrates modern startup advertising design with the feel of authentic paper and playful annotations."
