/* === LAYOUT BEHAVIOR ===
 *
 * Desktop (>768px):
 *   - Horizontal layout: scrollable content area + fixed-width sidebar
 *   - Sidebar hidden by default, slides in from right when .open class added
 *   - Desktop X button in top-right corner to close
 *
 * Mobile (≤768px):
 *   - Vertical layout: content fills screen
 *   - Sidebar is a slide-up drawer from bottom (60vh height)
 *   - Drawer hidden by default, opens when .open class added
 *   - Drawer has close button and backdrop overlay
 *   - Horizontal scroll disabled, navigation via carousel buttons using transform
 *
 * === STICKY HEADER ===
 *   - Two rows: logo/info row + filter bar
 *   - Both rows stick together at top when scrolling
 *   - Logo on left, newsletter link + contact email on right
 *   - Same horizontal layout on mobile and desktop
 *
 * === FILTER BAR ===
 *   - Horizontal flex, scrolls horizontally on overflow
 *   - Inside sticky header
 *   - Dropdown menus scroll if content exceeds max height
 *   - Clicking overlay (visible when dropdown open) closes dropdowns
 *
 * === DATA GRID (#table-container, grid view) ===
 *   - width: max-content so the grid is wider than viewport
 *   - Carousel JS applies transform to #table-container to scroll columns
 *   - On mobile: .content is overflow-x hidden, carousel is the scroll mechanism
 *   - On desktop: .content overflows naturally (no carousel shown)
 *
 * === LIST VIEW (#list-container) ===
 *   - Separate element, no connection to carousel
 *   - Each tool-type section has its own independently-scrollable row
 *
 * === MOBILE CAROUSEL ===
 *   - Fixed < > buttons at bottom of screen
 *   - Jumps one column at a time via CSS transform on #table-container
 *   - Hidden when sidebar drawer is open or list view is active
