/* EMC Robotics — shared chrome.
 *
 * The design system is Engineersmind's, taken from prototype-em.html: black
 * canvas, Space Grotesk set uppercase for display, Manrope for body, and the
 * brand gradient (teal -> cyan -> violet) used sparingly as an accent rather
 * than as a fill.
 *
 * This file is DARK ONLY. The previous version carried a light theme and a
 * prefers-color-scheme switch; the brand does not have a light mode, and
 * keeping a second set of tokens alive that nothing designs against is how
 * they drift. One canvas, one set of values.
 *
 * demo.html does NOT load this file. It carries its own copy of the tokens
 * inline, because it must render its first frame before a stylesheet arrives —
 * a simulator that flashes unstyled looks broken in exactly the way the page
 * exists to argue against. Keep the two in step.
