/* ============================================================================
   SNS shared quick-look card — D-EXPCARD-0716 §1 (Q-EXP-1, 2026-07-16)
   ----------------------------------------------------------------------------
   The ONE sitewide drill-down/quick-look standard. Structure:
     .exp-scrim > .exp-card > (.exp-close, [.exp-head], .exp-body, [.exp-actions])
   Loaded per-route via explicit <link> on opt-in routes (NOT chrome-injected).
   Deliberately UNLAYERED: legacy exp-* rules live inside @layer components in
   core.css (dashboard, pre-extraction); unlayered rules win the cascade, so
   every structural property the legacy rules set is restated here.
   Sizes/breakpoint extracted from PR #2632 (merged main). Scrim, ✕≥44px,
   64px head, gray border per D-EXPCARD-0716 §1.
