      lex: "Renders the schedule of an event as one SVG per day: a grid with one column per room used that day, boxes placed at their real clock positions. The figure is fitted to the panel it is shown in, which is at most 1320px wide, so anything wider is scaled down until its text is unreadable: thirteen rooms at the fixed pitch of 176 came to 2346 units and 5.5px type. The pitch is therefore divided out of a width budget as soon as a day has more rooms than fit at 176, and the time axis is compressed as soon as the day runs longer than the height budget; seven rooms and 333 minutes still get the old values, so every day that already fitted is drawn exactly as it was. Covers both the presentations that are part of the event and its workshop, tutorial and session sub-spaces, which are coloured differently and link to their own space pages. The per-slot ranking joins two separately computed sub-selects rather than filtering a cross product, which the engine evaluated as a nested loop; the room\'s column index and the day\'s room count now come from one such pass as well, instead of a second one. Box text adapts to the box and to the column: an author line and up to seven title lines, one more for every twelve pixels the box has beyond the first two, otherwise a single centred title line with the full title and authors as a hover tooltip, and no text in boxes too short for one line. Line length follows the column width, derived from the widest character of the real font, and a line that has to break inside a word resumes at the next character. Reads both the http:// and https:// schema.org namespaces. Where several valid nanopublications introduce the same talk or sub-space (e.g. an override published by another admin, which carries no supersedes link), only the most recently created one is used, so an item is never counted twice. Each box links with an explicit &context= naming the event, so that a talk opened from the schedule lands with the conference as its navigation context; without it Nanodash appends the context of the page the schedule happens to be rendered on, and from the schedule\'s own resource page that is the schedule, on which the part page renders none of its views."
