   LANDINGPAGINA & STANDALONE PAGINA'S
   Hier staat wat voorheen in static/home.css stond. Deze pagina's
   breiden niet uit van base.html en dragen daarom <body class="standalone">.
   Hun eigen kleuren heten --home-* zodat ze de app-variabelen (--primary,
   --card-bg, ...) niet overschrijven. Regels die een selector uit het
   app-gedeelte raken staan als ".standalone ..." zodat de app zijn eigen
   versie houdt; de app laadt deze pagina's nooit.
