/* Desky — a departure board for a term.
 *
 * The subject is a timetable, so the page is built like one: time in a gutter
 * down the left, hairline rules between rows, alignment doing the work boxes
 * used to do. Everything is quiet except the one thing that is next, which is
 * the only filled block on the screen.
 *
 * What was taken out, and why:
 *   - Every label was UPPERCASE and letter-spaced. Fourteen of them on one
 *     screen, none of them carrying information.
 *   - Every element was a rounded card with the same radius and border, so
 *     nothing looked more important than anything else.
 *   - Meta was chained with middle dots: "Lecture · Trottier 2110 · 16:05".
 *     Position says the same thing without the punctuation.
 *   - Panels faded and slid up on every single tab change.
 *   - There was no desktop layout at all.
