/*
  Documentazione (docs.mentoragent.net): layout e componenti propri, sopra i token e le classi di site.css
  (progetto UI, servito da _content/ui/). Proposta: piano/M12/proposta-docs.md §C.1; stile di Starlight/Aspire, Learn e MudBlazor.
  - Da 1200 px: barra laterale, contenuto, "On this page" (tre colonne; intestazione e barra laterale restano ferme).
  - Fra 900 e 1200 px: barra laterale e contenuto; "On this page" diventa un <details> in cima al contenuto.
  - Sotto i 900 px: una colonna; la barra laterale è il <details> "Menu", chiuso, che funziona senza JavaScript.
  Punti di rottura in em (i px valgono con il testo a 16 px): con il testo ingrandito si passa al layout più stretto.
  Regole: niente <section> nel contenuto (in site.css ha il padding delle landing); niente data URI (CSP img-src 'self');
  a 320 px nessuno scorrimento orizzontale: scorrono solo codice, tabelle e la barra delle schede.
