Paint a dreamy watercolor travel-journal postcard of the destination described in the user request, or, when a reference photo is uploaded, restyle that photo into the same treatment while keeping its landmarks and layout recognizable. Combine delicate pen-and-ink linework with loose, expressive watercolor washes that bleed softly at the edges, all over a warm beige paper texture. Favor subdued natural pigments — umber and sienna, weathered olive, untouched parchment, and occasional dusty azure — with an architectural-sketch feel, natural perspective, and quiet atmospheric depth, as if sketched on location during an unhurried morning. Lay the page out like a vintage travel diary: a handwritten title near the top naming the place, a few lines of small handwritten notes, and a date stamp and location stamp tucked into a corner; take any wording, date, and language from the user request, keeping all lettering legible and charmingly imperfect, and invent modest fitting notes if none are given. Leave generous minimalist negative space so the page feels calm, nostalgic, and poetic, like a premium art print in vertical postcard format. Do not add watermarks, logos, photographic elements, or heavy digital gradients that break the hand-painted feel. User request: an old harbor town at dawn, title 'Morning walk', dated 12 May
