Interactive vintage-shirt concept website with cursor-following mascot

GOAL: Build "Coconut Button Club", a concept shop for vintage aloha shirts, as a static website (plain HTML, CSS and JavaScript, no build step), using the attached painted character illustration as the hero and brand mascot. MOTION: The character is "Big Lou, head of shirts". THE HERO: LOU FOLLOWS YOUR CURSOR Lou turns his head to look at the visitor's cursor. Do not use a 3D model or face tracking. Build a 2D pose grid instead: 1. Upscale the illustration and outpaint it wide enough for a desktop hero, keeping the original figure untouched. 2. With an image-editing model (Nano Banana Pro), make 8 head-pose keyframes from the original: turned left and right, tilted up and down, and the four diagonal corners. Hair, face, shirt and art style must stay identical. 3. With an image-to-video model (MiniMax H3 at 2K), make 5-second start-frame/end-frame clips that sweep the head between poses while the body stays perfectly still. Add extra tilt clips if the level-to-down step is too big. 4. Assemble a grid of 152 poses (8 heights x 19 angles). Pick frames by measured eye position, not by time, so every step is the same size. Cut each head out with a feathered mask and composite it onto one fixed body so the shirt never jitters. Fill the in-between rows with optical-flow morphs. Export as 8 WebP pose strips plus a rig.json holding per-pose eye positions and skin tones. 5. At runtime the cursor sets a target yaw and pitch, a soft spring chases it, and the nearest pose is painted on a canvas placed exactly over his head. Paint blinks and the occasional wink live, using the eye positions and skin tones from rig.json. PAGE SECTIONS - Header and nav, with a bag. - Hero: "Loud shirts for quiet afternoons." with Lou in the cursor-following rig. - The Rack: generated shirt illustrations (Big Lou, Koi Pond, Lava Flow, Night Orchid, Pineapple, Surf Club) hung on a rail you can drag. They swing like shirts on hangers, with physics. - "How to spot a real one": a field guide to a vintage aloha shirt, with hotspots on an annotated illustration. - The shore: "Every shirt on the rack has been to the beach at least once." over a looping painted beach (an image-to-video loop whose first and last frames match the still, so it loops seamlessly). - "Join the club." footer: a newsletter form, with a second Lou peeking up from the bottom of the page. LOOK AND FEEL A warm, painterly vintage-resort feel: cream paper, red, palm green, film grain. Fonts: Fraunces for display, DM Sans for text, DM Mono for labels. Add scroll reveals and gentle motion, and respect prefers-reduced-motion. The bag and the form are for show and send nothing. State that it's a concept. Before building, propose the concept and list the assets you'll generate with their prompts, then generate the assets, then build the site. Check the head rig in a browser: it must look like one continuous painting turning its head.
