   Sistema de rachas: hover-card + modal + popup (variante mobile).
   Extraído de learning.css y responsive.css en Round 1.3.

   NOTA: Los dark mode overrides ([data-theme="dark"] .streak-*) siguen
   en learning.css por ahora — funcionan vía mayor especificidad.
   Las referencias pequeñas dispersas (.streak-badge en dashboard,
   .streak-visual-* en dashboard, .stat-streak-stat en learn topbar)
   se moverán con sus páginas respectivas en Round 3.
