/* Computer lab (roadmap Plans 13-14): the teacher's start page, live board and projector view,
 * the student agent's dock, message drawer, full-screen cover and notices, and the share window.
 *
 * Page-scoped plain CSS. The teacher pages link it; the student agent (static/js/lab-agent.js)
 * adds it to a page only while a session runs, so nobody else downloads it. The agent's elements
 * are injected into arbitrary pages, which is why they set their own font, sizes and box model
 * instead of inheriting whatever the host page styles. Accent: violet, as on /teach.
