16:9, 2x2 grid, do this for an unusual but real classic motorcycles INPUT = [ TOPIC / HERO_OBJECT / BRAND_TEMPERAMENT / VIEWPORT / GRAVITY_LAW ]
Run HERO_PRODUCT_GRAVITY:
TOPIC_DNA := infer the category from TOPIC alone — what's sold, who buys it,
what its shelf looks like
HERO_DNA := ONE photographic hero object, cut out, oversized, 30–40% of frame;
real material response — specular on foil, matte on paper,
subsurface scatter on skin or fruit
BRAND_DNA := derive the palette FROM the object — 1 dominant, 1 accent pulled
from a hue the object actually contains, 1 near-neutral ground
LIGHT_ANCHOR := decide key light position ONCE (upper-left or upper-right); every
shadow — object, cards, pills, floating confetti — falls the same
direction at the same angle and softness
GRAVITY_LAW := the hero is either GROUNDED (contact shadow touching a visible
surface plane) or SUSPENDED (ambient occlusion beneath, blur growing
with height) — never both, never floating with a hard cast shadow
and no plane to cast it onto
DEPTH_ORDER := ground wash < decorative rays/confetti < hero object < UI chrome.
Nav, cart and buttons are ALWAYS in front, never occluded
TYPE_LOGIC := one display face for the headline (heavy — pick condensed OR wide,
not both), one neutral for everything else; headline ≤ 6 words,
body renders as legible micro-type, never enlarged gibberish
IMPERFECTION := exactly one element breaks its bounding box — a badge rotated 4–7°,
a sticker overlapping the product silhouette, a stray mark in the gutter
FRAME := desktop 16:10, 64–80px outer gutter; the bottom edge reveals the top
15% of the next section so the page reads as scrollable
MOOD := appetite, immediacy, one unmistakable action
Render: one screen where the product's own light governs every pixel of interface around it.
Forbidden — objects: stock-photo humans, lorem blocks at display size, a second competing hero
Forbidden — look: conflicting shadow directions, cut-out halo or chewed edges, cast shadows
on flat 2D illustration, palette colors absent from the object, three type families,
nav bar sitting behind the product
