「DECEMBER 2026」は、静かな冬の植物風スタイルの2026年12月のスマホ壁紙カレンダーです。濃い緑のテクスチャ背景に、雪をかぶった松の枝と赤い実の下へクリーム色のセリフ体の大文字を配し、日曜始まりの表で25日を赤い丸で囲んでいます。月、年、強調する日付、枝の色を自分用に変えて作り直せます。

Create a finished vertical 9:16 Christmas phone wallpaper. Keep the top 28% calm and low-detail for a lock-screen clock: deep, softly textured spruce-green with only a few faint, sparse snow flecks near the edges. In the middle, place one elegant snowy pine branch, gently arcing from left to right, with fine needles, delicate white snow on its upper surfaces, and a few tiny muted-red berries. Keep it clearly above the calendar and away from the quiet clock zone. Set a precise, legible December 2026 calendar in the lower half, centered within generous safe margins. Use a warm ivory calendar area with no heavy box or distracting grid; align every weekday and date in seven evenly spaced columns, Sunday through Saturday. Render exactly these lines of text, with the same spelling and order: “DECEMBER 2026” “SUN MON TUE WED THU FRI SAT” “1 2 3 4 5” “6 7 8 9 10 11 12” “13 14 15 16 17 18 19” “20 21 22 23 24 25 26” “27 28 29 30 31” Place the first row's 1 under Tuesday; align every subsequent date under its correct weekday. Circle only 25 with a fine, hand-drawn cherry-red ring in the Friday column of the fourth date row; keep the numeral inside the ring and clearly readable. No extra greeting, caption, clock, device frame, widgets, icons, or other words. Use refined, highly legible display lettering: the month heading in elegant uppercase serif, the weekday labels in small, crisp uppercase, and the numerals in a clean, open serif with distinct shapes. Warm ivory ink contrasts against spruce green; the 25 ring is cherry red. Quiet vintage botanical Christmas illustration, restrained and airy, soft even light, subtle paper grain, delicate snow on the branch, no bright hotspots. Keep all lettering and key artwork comfortably inside the screen-safe margins.
