/* Ancho del contenedor general (2026-08-09, monitor real del dueño 1920x1080).
   1080→1400 fue el primer paso, quedaba mucho margen todavía con el rail
   lateral nuevo restando 84px; 1400→1760 después de verlo en pantalla real
   (deja ~28px de aire de cada lado en 1920px con el rail, en vez de ~220px).
   `width:100%` es necesario desde que .wrap pasó a ser grid-item de
   body.has-rail (nav lateral, mismo día): con margin:auto pero sin width
   explícito, un grid item no se estira solo — se achica al tamaño de su
   contenido (fit-content) en vez de llenar la columna 1fr disponible, dejando
   un montón de espacio vacío a la derecha. Con width:100% vuelve a ocupar
   toda la columna y el max-width sigue funcionando como tope. */

/* ---- Lección de curso (courses/lesson.html) — propuesta A, 2026-11-04 ----
   Capítulos | tablero | un solo panel (cabecera / jugadas con scroll propio / barra fija).
   El tablero sale del ALTO de la pantalla y los dos costados miden lo mismo que él.
   Anchos medidos contra Lichess Study (350 · 835 · 389 a 1920) y el lienzo de Estudio.
   - 3 columnas si el tablero queda en 620 px o más (>= 1342 px de contenido);
   - 2 columnas debajo de eso: los capítulos pasan a la pestaña "Capítulos" del panel;
   - apilado (celular/tablet vertical): tablero arriba a lo ancho, panel debajo hasta el
     final de la pantalla, sin scroll de página; la lista se acomoda sola a la jugada. */
