+This module keeps attributes that never generate a variant (attributes
+with their *Variant Creation* setting on *Never*, e.g. purely
+informational specs) out of the website product page's variant selector,
+and out of the combination-exclusion rules used to gray out incompatible
+options.
+
+Without this module, an informational attribute's value can still
+exclude a real, variant-defining value through a configured *Exclude
+for* rule, even though the informational attribute itself is never shown
+to the shopper as a selectable option — resulting in a visible option
+being grayed out because of an attribute the shopper cannot see, with a
+tooltip naming it.

+
+Usage
+=====
+
+This module requires no configuration: it applies automatically to every
+product attribute whose *Variant Creation* is set to *Never*.
+
+1. On a product, add an attribute with *Variant Creation* set to *Never*
+   (e.g. an informational spec such as a material or a care
+   instruction), alongside your normal variant-defining attributes.
+2. Optionally, configure an *Exclude for* rule on one of that
+   attribute's values, targeting one of the variant-defining values.
+3. Open the product page on the website: the informational attribute no
+   longer appears in the variant selector, and the variant-defining
+   value targeted by its exclusion rule is no longer grayed out because
+   of it.
+4. Add the product to the cart: the hidden informational attribute never
+   blocks *Add to Cart*, even when its excluded or default value would
+   have conflicted with the one visibly selected.
