Create a complete square birthday card for a girlfriend, with a vivid, high-energy party scene and carefully rendered, readable lettering. Use exactly these text strings, with no additional text: primary name “Janu”; secondary greeting “HAPPY BIRTHDAY”; supporting line “Every day is brighter with you.”; small closing “All my love”. Arrange the greeting above the name, with the name as the dominant center headline. Set all lettering in contemporary signature calligraphy with continuous pressure-curve construction: fine entry points swelling gradually into broad downstrokes, near-hairline connecting upstrokes, smooth organic transitions, and wide arcing capital swashes that taper and rejoin the letter bodies. Preserve graceful, fluid letterforms rather than converting them to block lettering. Render the strokes in glossy, vivid candy colors with bright internal highlights, subtle dimensional depth, and a crisp white outline for contrast. Build a stacked card composition: the greeting occupies the upper 10–15%; “Janu” fills about 55% of the central area; a small illustrated heart-shaped birthday cake with a single lit candle sits below the name; the personal message and closing form two short, centered lines in the lower quarter. Frame the typography with generous clusters of saturated pink, orange, turquoise, and violet balloons at the sides, plus a dense but controlled burst of multicolor confetti, sparkling glints, and short light streaks. Use a luminous hot-pink-to-turquoise party gradient with rich color contrast; keep the background bright, never pale, grey, or dark. Arrange decorations around clear text zones so every line remains legible. Polished dimensional illustration, crisp edges, bright party lighting, high-resolution finish.
