   css/tabla-funciones.css · la «Tabla de funciones» (v1.128)
   Msc. Néstor Fabio Montoya Palacios · Estudio Científico Pro · 2026

   Solo la tabla NUEVA (región `table` con la clase `esci-tf`, ver
   js/regions/table-region.js); la tabla de siempre conserva su aspecto, que
   vive en css/regions-data.css y css/regions-texto.css y NO se toca aquí.
   El diseño aprobado está en Claude outputs/tabla-funciones-v1-128/DISENO.md
   y su boceto. Los números van en la letra de KaTeX (dígitos del mismo ancho)
   partidos en parte entera y decimal para alinear por la coma, como en los
   libros; los símbolos (nombres, fórmulas, unidades) los pinta KaTeX.
   Tableta (`pointer: coarse` o menos de 820 px): todo control mide 44 px.
