Ultra-Dense Japanese Maze Puzzle

Create a square black-and-white puzzle poster in the style of an extremely intricate hand-drawn notebook maze, clean monochrome ink on white paper. At the top center, place a bold Japanese headline reading headline_text in a Mincho-style serif font. Below it, fill almost the entire page with one huge rectangular maze inside a thin double-line border, made from thousands of tiny orthogonal corridors, micro-grid strokes, dead ends, and tight right-angle passages, like a 2026 upgraded version of a middle-school original maze. The maze should be overwhelmingly dense and difficult, with no color and no shading except black linework. Include exactly 15 larger embedded maze motifs visible within the dense field: 4 concentric square spiral targets, 3 circular spiral targets, 2 large X-shaped starburst maze structures, 1 tall rectangular diamond/chevron maze block, 1 central nested-square pyramid-like maze, 1 large asymmetric diamond spiral maze in the lower-left center, 1 large diagonal crossing X near the lower center, and 2 horizontal ladder/grid maze blocks. Add faint long straight divider-like corridors running vertically and horizontally through the maze, plus diagonal corridor cuts, while keeping every area packed with tiny solvable-looking paths. Overall composition: crisp scan-like puzzle sheet, centered, high contrast, no illustrations, no characters, no gradients, no background texture beyond the maze lines.
