Clean up the stylesheet, add a pages directory for single-page styles to include in the app.css.

• inc/
  • frontend.css

To include it in the app.css use @import:

/* Layouts */
@import "./inc/layouts/frontend.css";
@import "./inc/layouts/dashboard-host.css";
@import "./inc/layouts/dashboard-guest.css";

/* Components */
@import "./inc/components/calendar.css";
