Left side (~52%) shows a wide snowy alpine mountain landscape with conifer forest and overcast sky, slightly desaturated cool-neutral grading, masked by a large smooth curved shape. Add very subtle snow/bokeh particles mainly over the photo area, keep the right side clean. Right side (~48%) is bright white negative space with a large teal "2" at the top-right and bold "FEBRUARY" centered below. Place a rounded white calendar card with a light border and soft shadow at center-right. The calendar is Sunday-first (SUN MON TUE WED THU FRI SAT) and must be correct for February 2026: weeks are 1–7, 8–14, 15–21, 22–28. Sundays are red (SUN header and all Sunday dates), Saturdays are blue. Highlight dates 11 and 23 in red. Bottom-left on a layered deep-teal flat wave band, place "CALENDAR" and "2026" in bold white sans-serif. Between the photo and white area, use a thin flat 2D curved teal gradient splitter band (no 3D, no bevel, no glass, no facets).
