/* MPS Mining - hoja de estilos base, basada en tokens. IDENTIDAD ACTIVA: D1 "Calma Petroleo" (docs/competencia/DIRECCION-EJECUTIVA.md, docs/BRANDING.md).
   CAMBIO DE PALETA = cambiar UN bloque: los tokens --color-* del primer bloque :root. Las paletas antiguas (actual navy+oro, calma, calida) se retiraron; el comparador historico es assets/brand/paleta-preview.html.
   Reglas D1: aqua (--color-cta) solo como boton sobre bloques oscuros; sobre fondos claros el boton es petroleo solido (--btn-bg) u .outline; el aqua claro (--color-accent) es decoracion/texto SOLO sobre oscuro; sobre claro se usa --color-accent-ink.
   Contraste AA verificado con calculo (tabla en docs/BRANDING.md, "Decision: D1 aplicada").
   Capas: 1 tokens (paleta) - 2 tokens estructurales (espacio, radio, sombra, movimiento) - 3 alias heredados - 4 componentes. */
