   Los íconos viven en /img/icons/phosphor.svg como <symbol>. El
   componente <x-icon> los referencia vía <use href="...#name">.
   Cada <symbol> tiene 2 <path>:
     - El primero con opacity="0.2" (relleno duotone)
     - El segundo sin opacity (trazo)
   Ambos heredan fill="currentColor" del <symbol>. Por eso basta
   con cambiar `color` para repintarlos.

   §28 STEPS-N — extensión responsive de kd-steps-3 para N etapas
   Sprint 2.6 — usado por components/steps-n.blade.php.
   ----------------------------------------------------------------
   Diferencias vs .kd-steps-3:
     - Auto-fit con minmax(180px, 1fr) en vez de columnas fijas
       → 5 etapas en desktop wide, 3 en mid, 2 en tablet, 1 en mobile
     - Sin línea conectora horizontal (con N variable la línea se
       desalinea entre breakpoints — el flujo se infiere del número
       grande en cada paso)
     - Gap más compacto que steps-3 (space-8 vs space-10) porque las
       columnas son más densas cuando hay 5+ etapas.

   Reusa todas las clases hijo: .kd-step, .kd-step-number,
   .kd-step-icon, .kd-step-title, .kd-step-desc — definidas en §15
