A non-exhaustive sample of the templates this system actually uses, to give a sense of the range:knot is the plain default view, rendering a knot's content and its children as an ordinary document.mainframe turns a knot and its children into a live, broadcastable slide deck, with optional audio narration, a classroom-cast mode, and cross-referenced-knot preview-on-hover.reveal2 is an older slide-deck template built directly on reveal.js.semester renders a whole course's session list, including a 'live' badge for whatever is currently being cast.play and read are built around spoken-word recordings linked via is_uttered_as and illustrates.arbre renders a knot's neighbourhood as a graph diagram.Separately, several domains each define their own fixed canonical template (console, treehouse, arena, atlas, and so on) that every .knot-suffixed URL on that domain uses regardless of the knot's own template attribute -- see domain_template in config.yml.
