Interactive Product Configurator UI Prompt

2x2 grid, 16:9, do this for 4 rare unusual collectibles before 1890s: INPUT = [ PRODUCT ] Instructions: INFERENCE_CASCADE := derive 3–5 real OPTION GROUPS → 2–6 choices each → which combinations are impossible → base price and honest per-option deltas → the default a first-time buyer lands on STATE_TRUTH_LAW := the render and the controls are ONE fact. Every active selection is visible on the product; every visible feature has an active control. Unavailable combinations are disabled and visibly so. The total equals base plus the selected deltas - do the arithmetic and show it. GROUP_LOGIC := exactly one active state per single-select group; multi-selects visually distinct from single-selects (checks vs pills) PREVIEW_DNA := one large product view holding a constant camera and light across all configurations, so only the configured parts change SWATCH_FIDELITY := each swatch's color/material is the SAME sample rendered on the product LIVE_FEEDBACK := one element proves interactivity - a hovered swatch, a just-changed price with its previous value struck, a spec line updating CONSTRAINT_MESSAGE := one plain sentence explaining a disabled option IMPERFECTION := one option mid-transition, a tooltip open, the cursor placed to explain it FRAME := 16:10; preview left, controls right rail, sticky summary bar MOOD := control without confusion Render: one screen where the controls and the object cannot disagree. Forbidden - objects: decorative options that change nothing, invented spec categories Forbidden - look: two actives in one group, a total that doesn't sum, a swatch color absent from the render, camera or light shifting between configurations, disabled states that look identical to enabled ones
