/*
 * Pagina di materia — the container of a subject's schede (D-061, D-186).
 *
 * Colours, type sizes and spacing come from theme.json presets, never as
 * literals: a hard-coded colour here would survive a palette change and quietly
 * contradict it, which is what D-219 was about.
 *
 * This page is a list to scan, not prose to read, so it uses the full page
 * width instead of the scheda's single column: the eye runs down titles, and a
 * narrow measure would only make the list longer.
