/*
 * Kaally Bundle & Save — Module B cross-sell block (v1.3.0)
 * Full stylesheet (progressive enhancement over the inline fallback in
 * kbs_b_get_critical_css() inside includes/module-b-crosssell.php).
 *
 * Brand tokens: mauve #6B5A5B, cream #F7F1E8, brown #5D4A3A.
 * Font stack: Lato body, Libre Baskerville headings.
 *
 * IMPORTANT: If you update styles here, keep kbs_b_get_critical_css() in sync.
 * The inline block is the LiteSpeed UCSS safety guarantee for logged-out visitors.
 *
 * Layout change in v1.3.0:
 *   - Replaced checkbox layout with "+ Add" button row layout.
 *   - Each add-on row: thumb | info (name + was/now price) | "+ Add" button.
 *   - Locked variable add-ons show a static "locked label" under the name.
 *   - Variation picker still appears below the row for non-locked variable add-ons.
