可爱兔子平假名海报

Create a cute Japanese preschool hiragana poster in a soft watercolor storybook style on warm textured parchment paper. The composition is a vertical educational chart with a whimsical spring border of grass, flowers, mushrooms, butterflies, and tiny chicks, designed like a children's classroom learning sheet. At the top, place a wooden signboard header with colorful rounded Japanese text reading {argument name="headline text" default="うさぎのひらがな表"}, decorated with 2 white bunny mascots, one sitting on the left and one peeking from the right, plus small flowers and leaves around the sign. Below the header, arrange a clean 5-row by 8-column grid for a total of 40 square cells, each cell outlined in thin brown lines on a cream background. In every cell, place one large brightly colored hiragana character near the top and one small kawaii rabbit illustration below it, each rabbit acting out or holding an object associated with the word written underneath. Use a different cheerful color for many of the hiragana characters, including reds, oranges, yellows, greens, blues, and purples, with a hand-painted rounded font. Keep the text and illustrations exactly as follows, left to right by row: row 1 has 8 cells labeled あ, い, う, う, え, え, お, お with the words あめ, いい, いい, うさぎ, えんぴつ, えんぴつ, おやすり, おにぎり; row 2 has 8 cells labeled か, き, く, け, せ, せ, そ, そ with the words きくら, たま, サベツン, ケーキ, せんせい, そう, そう, しょうこう; row 3 has 8 cells labeled た, ち, ち, つ, て, て, と, と with the words たまご, たまご, ちびこ, つと, てんとうむし, てしなを, とうこ, ほしい; row 4 has 8 cells labeled な, に, ぬ, ふ, め, ね, の, ほ with the words まな, ひこうき, みんきう, ふたう, てつ, へびす, ようこ, ほし; row 5 has 8 cells labeled ま, み, む, る, れ, れ, ろ, ん with the words わた, まくら, みかん, むぎぎ, めがみ, もも, ろうた, ん. The bunny illustrations should be varied and adorable: examples include holding an umbrella, cuddling grapes, drawing with a pencil, eating a rice ball, sitting with cherry blossoms, standing under an umbrella, holding fruit, eating cake, dressed as a teacher, holding flowers, sleeping under a blue blanket, carrying eggs, hugging a tomato, holding strawberries, blowing bubbles, wearing a blue cap, holding an orange, sitting with cotton, bathing in a wooden tub, and holding candy. Maintain a gentle pastel palette, soft shading, round faces, rosy cheeks, and subtle ink outlines. The overall feeling should be nostalgic, charming, educational, highly detailed, and perfect for a nursery wall chart or a cute slide cover for a Japanese learning presentation.
