 * .lb-section) are kept as selector aliases so legacy markup keeps
 * working; new screens should prefer .card.

 * Card variants:
 *   .card           — default slate-tinted panel
 *   .card-flush     — no padding (caller owns the inner spacing)
 *   .card-emphasis  — slightly stronger background + shadow
