/* ============================================================================
   MANUALE — overrides che adattano il CSS dell'app a un documento di lettura.
   Il manuale carica gli stessi 6 file CSS dell'app (vars/layout/components/
   sections/themes/responsive) e poi questo override per:
     - larghezza contenuto stretta (50-72ch, ottima per leggibilità prosa)
     - formule in <pre.formula> con sfondo paper-2
     - esempi numerici in <table.example>
     - link interni del TOC più visibili
     - nascondere componenti dell'app che non servono (theme-switch, masthead state-toolbar)
