Create ONE finished printable child bedroom nameplate. Default landscape A4 (297 x 210 mm). The entire canvas is the flat front-facing print artwork, never a photographed paper, door mockup, collage, or physical object. If a different canvas ratio is explicitly supplied, adapt the layout to that ratio. No reference photo is needed; do not turn attached photos into portraits.
NAME: "【子どもの名前】". Render this exact name large at center. Empty name means "Haru". Never invent a surname. Long names shrink only enough to remain on one line.
SUBJECT: "【好きなもの】". Empty means 恐竜. Draw small original illustrations of that subject at corners without overlapping text. Space means planets and spacecraft; flowers means botanical bouquets; cars means fictional toy car designs. Never reproduce existing characters or branded product shapes.
MOOD: "【雰囲気】". Empty means パステル水彩.
- パステル水彩: pastel watercolor washes, mint cream peach, soft pigments and friendly rounded original shapes.
- かわいい手描き: warm ivory peach yellow, colored pencil and gouache, charming hand drawn details.
- ナチュラルな木目: flat light birch wood grain printed background, dark brown typography and restrained teal orange illustrations; no photographed wood or bevel.
- 鮮やかな漫画: vivid crisp cartoon shapes, navy yellow turquoise colors and clean bold contours.
SMALL LINE: "【小さな一行】". Define SUBTITLE once: when the selection is "Haruの部屋", "おまかせ" or empty, SUBTITLE is the selected name followed by の部屋. If "ノックしてください", use that exact phrase. If "なし", omit the subtitle and recenter the name. Otherwise use the supplied short sentence verbatim.
Print only NAME and SUBTITLE, each exactly once. Use Japanese lettering for the subtitle and preserve the supplied name verbatim. Big readable name centered at 30–65% height, smaller readable subtitle at 68–78%. Keep every letter clear of decorations. Put a thin decorative border safely inset; keep text at least 8% away from all edges. Artwork fills the canvas, with no exterior blank margins. Give name and subtitle strong contrast. Before finishing, check each letter against NAME and SUBTITLE without adding any checking notes to the image.
No people, real brands, logos, signatures, watermarks, recognizable fictional characters, extra text or promotional labels. Return the finished image directly; no code, cutting or postprocessing steps.
