A classy portrait birthday card in luxury gold foil on a deep, layered darkness. The background is a near-black to deep navy gradient with a faint soft vignette. A thin gold hairline border frame sits inset from the edges, with a second finer hairline just inside it. All lettering is in refined high-contrast serif capitals with wide letter spacing, rendered as genuine 24-karat gold leaf. The surface is warm matte-to-satin with subtle hand-applied foil variation, bright highlight along the top edges, deep amber shadow at the base, and slightly frayed micro-thin edges. Fine gold dust floats in the air. A warm spotlight from the upper right glints across the letters. Copy, centered on one vertical axis, every string exactly as written: 1. Top, small and delicate: "HAPPY", in widely spaced capitals about 22% of the card width. 2. Centre, the dominant anchor: a huge numeral "40th", the numeral in gold leaf at about 60% of the width, with a small elegant "th" raised beside it. Directly beneath it, "BIRTHDAY" in wide-tracked capitals at about 55% of the width. 3. Below this, a short gold hairline rule with one tiny gold diamond at its centre. 4. Bottom: "RAUTARUUKKI" in large wide-tracked gold-leaf capitals at about 70% of the width, so the honoree's name is clearly readable. Reading order is "HAPPY", then the 40th birthday, then the name. Place a maximum of 7 tiny gold four-point stars asymmetrically in the dark field, varied in size. Leave generous empty dark space around each tier. A soft, out-of-focus gold bokeh circle sits in the lower corner for depth. No confetti, no balloons, no colour other than gold on dark. The mood is a prestigious heritage-brand anniversary card with premium printed foil quality.
