/**
 * Electrical tape product story.
 *
 * Image-and-text modules built from the same data the text reads from.
 * Scoped under .story so nothing here can leak into the rest of the theme.
 *
 * Colour and spacing follow the theme's existing custom-property names where
 * they exist, and fall back to values that hold on their own if the token is
 * missing, so this file also reads correctly inside the exported static build.
