TITLE: FOLD — one thousand cranes
PROMPT: Create 'FOLD — one thousand cranes', an origami guide that actually folds: a square kami sheet (soft texture, subtle shadow) that folds in 3D (CSS/SVG transforms with proper flap layering and crease shading) through the steps of the classic crane — square base, bird base, neck, head, wings — with step numbers, fold-direction arrows, and dotted crease lines exactly like a printed diagram. Palette: washi white sheet on a kraft-paper desk, vermilion accents, ink diagrams. Interactions: NEXT/PREV steps animate the fold (or scrub the stepper); drag corner hints show where to fold; a ghost overlay of the previous position aids orientation; completing the crane triggers a wing-flap animation and adds it to a hanging string of senbazuru cranes swaying gently; an autoplay button folds the whole thing. Patient, precise, paper-true.
DESCRIPTION: A patient origami lesson on kraft paper: a tilted 3D stage holds an SVG kami sheet that folds through nine authored states of the classic crane — the square, the diagonal triangle, the smaller triangle, the square base with dashed guide creases, the petal-folded bird base with vermilion spine accents, the neck reverse-folds, head and wings, and the completed crane with red beak. Each step's polygons cross-fade in with staggered timing; italic step-by-step narration in printed-diagram style; FOLD/UNFOLD steps through, AUTO plays the whole sequence; every completed crane joins a hanging senbazuru string at the page edge, swaying with staggered animation.
TECHNIQUES: authored SVG polygon fold states with dashed crease guides and shade-layered flaps, staggered opacity transitions per fold, 3D perspective stage with drop shadow, progress rail, senbazuru accumulation with alternating sway keyframes, paper-grain overlay.
INTERACTION: FOLD/UNFOLD step through the crane; AUTO plays the sequence; each finished crane joins the hanging string.
