/* ============================================================================
   calc-base.css · Sistema de estilo unificado para calculadoras — LIF Poker
   ---------------------------------------------------------------------------
   Cliente piloto: Calculadora PKO.
   Cliente objetivo: PKO, 3bet vs OR, Bet Calculator, Risk-Variance Lab,
   y cualquier "calc" futura con la estructura
       [palancas izq · 340px]  +  [resultados der · 1fr]

   Premisa: NO redefinir tokens. Heredamos los del dashboard
   (`:root` en dashboard.html / dashboard-style.css):
       --primary, --accent, --deep, --primary-rgb, --accent-rgb,
       --surface, --surface-2, --bg, --bg-2,
       --text, --text-soft, --muted,
       --success, --danger,
       --card-bg, --border-color, --neutral,
       --font-display, --radius, --radius-sm, --ring,
       --ease, --t, --shadow-1, --shadow-2.

   Solo agregamos tokens *locales* prefijados `--c-*` cuando hace falta
   parametrizar algo por-calc (ancho de palancas, tamaño del número hero,
   tinte del bloque hero — ver `--c-hero-accent`).

   Convenciones:
     • Estado activo: `.is-active`  (consistente con chip-group: `.is-selected`,
       y con threebet-vs-or: `.is-active`).
     • Estado semántico: `.is-good`, `.is-bad`, `.is-neutral`, `.is-primary`.
     • Prefijo `calc-` para todo. Cada calc agrega su prefijo propio
       (`pko-*`, `tbvo-*`, etc.) en su CSS local solo para lo específico.

   Mantenimiento:
     • Si una clase termina sirviendo a >1 calc, vive acá.
     • Si es overhead específico, vive en `calc-<nombre>.css`.
