This splash birthday page is a puddle-jump pass built around a soft watercolour unicorn invitation. The card pairs flowing calligraphy with a painted unicorn umbrella and a bright blue puddle, and the page carries that rainy-day world through every section. The keepsake mat wears washi tape and a perforated splash-pass stub, a blue puddle band counts down to the party with frosted raindrop medallions, and the reply closes on a unicorn-umbrella mascot stage with a bright yellow splash button. Raindrops fall across a pale paper ground layered with soft watercolour washes in teal, pink and yellow, while splash drops and sparkles drift through the air. Every detail row — date, time, venue, reply date, attire and parking — is set in quiet geometric caps with a commissioned icon family drawn from the card's own imagery, and the section titles carry two-line kickers in the card's calligraphy voice. The milestone age reads as a co-headline beneath the honoree's name, and the countdown resolves from the invitation's own data so the page stays true for any host. Every surface of the page personalises at serve time: the honoree name, the turning age, the event date, the venue and the reply deadline all hydrate into their slots from the invitation's details, so a shopper sees the design exactly as their guests will. The page is built mobile-first, respects reduced-motion preferences, and ships with real venue directions and a calendar link for the demo event.
