Design a bold, functional monthly calendar with a dominant top-header layout. The top 25% of the page is a solid color block that changes monthly (e.g., Soft Sage #B2AC88 for Jan, Dusty Rose #D4A5A5 for Feb, Muted Teal #669999 for Mar). The Month Name is centered in this block in white (#FFFFFF) using ultra-bold Playfair Display serif at 80px. Below the header, the layout transitions to a clean white (#FFFFFF) grid. The day-of-week headers (S, M, T, W, T, F, S) are placed just below the color block in a matching accent color. The grid uses a 6-row structure with thin 1px borders in Soft Grey (#D1D1D1). Day numbers are in the bottom-right corner of each cell using Lato 400. Each cell is designed to fit 4 lines of text comfortably. No decorative icons, just the contrast between the saturated header and the clean writing space. Inspired by premium Japanese stationery brands.
