Minimalistische SaaS-advertentie met factuurmockup

Create a minimalist static SaaS ad on a warm off-white background with elegant editorial typography and clean, high-fidelity text rendering. At the top, place a large black serif headline in two lines reading: "{argument name="headline text" default="Your dev team shouldn’t be your analytics team."}" The words “dev team” should appear in italic serif while the rest remains bold high-contrast serif, with generous spacing and a luxury magazine-style layout. Centered below, show a slightly tilted white paper invoice sheet with a soft drop shadow and a subtle vertical fold crease down the middle, as if photographed from above. The invoice uses black monospaced typewriter-style text and reads exactly: “INVOICE — DEV HOURS, OCTOBER” as the header, then 5 line items with hours and prices aligned in columns: “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”. Under the 5 items, add a dashed divider line, then a bold monospaced “TOTAL” on the lower left and the total price “$4,950” on the lower right. Draw a hand-drawn yellow line striking through the total price. Add 4 doodle-style annotation elements around the invoice: on the left, handwritten yellow text saying “every month??” with a yellow arrow pointing right toward the paper; on the upper right of the paper, a yellow starburst scribble; below the total, a green curved arrow pointing up toward the crossed-out price; and on the lower right, a green hand-drawn circle containing the handwritten words “zero devs,” connected to the green arrow. At the bottom center of the ad, add a smaller black sans-serif body copy in 2 lines reading: “{argument name="body text" default="Marketers ship tests and track revenue themselves.\nNo tickets. No tag manager. One script."}" Keep the composition airy, premium, and conversion-focused, blending modern startup ad design with tactile paper realism and playful marker annotations.
