/*
 * deal-share.css — Share Deal Modal
 * Batch 47: Share modal overlay + card + form elements
 *
 * Zero hardcoded colors — all CSS custom properties from base.css.
 * Exception: .share-modal-overlay background uses rgba(0,0,0,0.5) — acceptable for overlay only.
 *
 * Animate in: .share-modal-card transitions from opacity:0 / scale(0.95) to opacity:1 / scale(1)
 *             via inline style set in deal-share.js (class `is-open` pattern used as fallback)
