 * Calculators — redesign to match Figma "rulr-team-library / Calculators &

 * Design tokens (from Figma variables):
 *   font           Inter Tight
 *   primary        #312e81  (indigo-900)  — links / "Open →" / active
 *   text           #020617  (slate-950)
 *   muted          #64748b / #4a5565
 *   card border    #f5f5f9
 *   card shadow    0 8px 24px rgba(33,33,97,.05)
 *   radius         16px (card), 12px (controls), 10.4px (icon tile)
