WooCommerce product attribute swatches

Use this skill when a plugin or theme needs to read, write, render, or audit WooCommerce visual product attributes. In WooCommerce 11.0 this is not a mature "classic variation swatches" template API. It is an experimental wc-visual product attribute type with color/image term metadata, consumed by selected block UI and optionally exposed by Store API.

Source-verified status in 11.0.0

• Feature ID: wc-visual-attribute.
• Feature option: woocommerce_feature_wc_visual_attribute_enabled.
• Default: experimental and disabled by default.
• Admin UI gating: the feature setting UI is disabled on non-block themes; wc_get_attribute_types() only exposes wc-visual when the site is a block theme with the feature enabled, or when the store already has an existing wc-visual attribute.
• Attribute type slug: wc-visual.
• Admin label: Color / image.
• Visual term value types: color, image, none.
• Supported core term meta: color hex string and image attachment ID. Image wins over color when both exist; core save logic deletes the other key.
• Classic single-product variable template still renders wc_dropdown_variation_attribute_options() selects. It does not output swatch buttons by itself.
• Store API visual data is opt-in and experimental: request __experimental_visual=true; response property is __experimentalVisual.
