// BDS CardsTwoColumn Pattern Styles
// Brand Design System - Section with header and 2x2 card grid
// Uses PageGrid for responsive layout
//
// Naming Convention: BEM with 'bds' namespace
// .bds-cards-two-column                    - Base section container
// .bds-cards-two-column__container         - PageGrid container with vertical padding
// .bds-cards-two-column__header            - Header row (title + description)
// .bds-cards-two-column__header-left       - Left column (title)
// .bds-cards-two-column__header-right      - Right column (description)
// .bds-cards-two-column__title             - Section title (heading-md)
// .bds-cards-two-column__description       - Section description (body-l, muted)
// .bds-cards-two-column__cards             - Cards row (2x2 on desktop)
//
// Note: TextCard styles are in shared/components/TextCard/TextCard.scss
// Note: PageGrid handles horizontal padding and column widths
//
// Design tokens from Figma (Section Cards - Two Column):
//
// Breakpoints:
// - Mobile: < 576px (min-width: 240px, max-width: 575px)
// - Tablet: 576px - 991px (min-width: 576px, max-width: 991px)
// - Desktop: ≥ 992px (min-width: 992px, max-width: 1280px)

// =============================================================================
// Design Tokens from Figma
// =============================================================================
// Note: Uses centralized spacing tokens from _spacing.scss.

// Section vertical padding (horizontal handled by PageGrid)

$bds-section-padding-y-desktop: $bds-space-4xl;  // 40px - spacing('4xl')

// Gap between header row and cards row
$bds-section-row-gap-mobile: $bds-space-2xl;     // 24px - spacing('2xl')
$bds-section-row-gap-tablet: $bds-space-3xl;     // 32px - spacing('3xl')
