/**
 * File: css/commerce-product-1.0.1.css
 * Version: 1.0.1
 * Date: 2026-03-07
 * Description: Drupal Commerce product detail page styling for drivenracing.com
 *
 * Actual DOM order inside article.commerce-product:
 *   1. .field--name-field-images > .field__items > .field__item (x7)
 *      - first = hero image
 *      - second = thumbnail
 *      - rest hidden
 *   2. .product--variation-field--variation_title__60441  (variation title)
 *   3. .field--name-body                                  (description)
 *   4. .product--variation-field--variation_price__60441  (price)
 *   5. .field--name-variations                            (add-to-cart form)
 *
 * Layout goal (matches D7):
 *   - Hero image: full width
 *   - Title below hero (dark, not blue)
 *   - Thumbnail floated left, description wraps right
 *   - Price + qty + Add to Cart below
 *
 * Change log:
 * - 2026-03-07 (v1.0.1) Fix selectors to match actual DOM structure.
 *                        Variation title uses product--variation-field class.
 *                        Images wrapper is .field__items not direct children.
 * - 2026-03-07 (v1.0.0) Initial release.
