/**
 * Single-product kitchen styles. Scoped to .lba-kitchen-product-page.
 * Hand-written, no frameworks. Depends on main.css tokens.
 *
 * Revision v1 (2026-04-21):
 *   - Middle section rewired to 2-column meta (primary + Maker sidebar).
 *   - Request-a-Quote CTA removed.
 *   - Old bottom Maker block removed (.lba-brand-editorial).
 *   - Tabs reduced from 4 to 3 (Design Process extracted).
 *   - Dedicated Design Process section added, mirroring Kitchens landing
 *     page Our Approach treatment, scaled to 4 columns.
 *
 * Revision v2 (2026-04-21):
 *   - Meta section collapsed back to single-column, left-aligned.
 *   - Right-column Maker aside removed; Maker moved to 4th tab panel.
 *   - Gallery hero converted from <div><img></div> to <button><img></button>
 *     with cursor: zoom-in to signal the PhotoSwipe lightbox.
 *   - New .lba-cab-tab-panel--maker rules give the tabbed Maker block
 *     breathing room and a logo-forward layout.
 *
 * Revision v3 (2026-04-22):
 *   - The Maker tab removed entirely; back to 3 tabs.
 *   - .lba-cab-tab-panel--maker rules deleted.
 *   - Tablet-only Maker logo sizing deleted from the 1024px breakpoint.
