/**
 * Pattern: Share Component  (patterns/share-component.php)
 *
 * Reusable share button for any single post/CPT (kd_event, blg_story, post).
 * Uses the native Web Share API with a copy-link clipboard fallback.
 *
 * Anatomy:
 *   .kd-share          — outer wrapper (white background, centred section)
 *   .kd-share__inner   — constrained, centred flex row
 *   .kd-share__btn     — icon + label button (outline pill, BLG secondary style)
 *   .kd-share__icon    — share SVG, 20×20, inherits currentColor
 *   .kd-share__label   — "Share" text label
 *   .kd-share__confirm — live region: "Link copied!" confirmation message
 *
 * Design source: Figma 23:1752 node 40:4923 (share-network-fill icon, 32px,
 * positioned at the right edge of the hero). The pattern renders it as a
 * labelled section at the page bottom for accessibility — positioning it
 * absolute in the hero would require !important overrides and break keyboard flow.
 *
 * Auto-enqueued by inc/enqueue.php glob over assets/css/patterns/*.css.
 * One pattern = one CSS partial. Prefix: .kd-share__*.
