/*
 * "Arma tu Block" configurator and product gallery (#92, #265, #256).
 *
 * Every look-and-feel value is a CSS custom property that maps to a theme.json token
 * (`--wp--preset--*`, `--wp--custom--*`, design.md §3-5). The fallbacks are neutral system values
 * so the form stays usable under another theme; they are not design decisions. The sizes
 * (44/48 px targets, 12/16 px radius, 1.5 px borders, 6 px progress segments) are the artboard
 * values of docs/design/mockups/Product.dc.html and Mobile.dc.html.
 *
 *   --blk-text      Tinta        --blk-surface   Blanco       --blk-surface-alt  superficie secundaria
