/**
 * Stylesheet of the public msc.eng.br website (pages built with includes/site.php).
 *
 * Dark theme taken from the application itself: a near-black workspace, thin
 * luminous linework and the selection yellow as the single action colour.
 * Motion is limited to one entrance sequence in the page banner, a gentle
 * reveal of each section on scroll and short hover/focus transitions; all of
 * it is switched off under prefers-reduced-motion.
 * Legacy pages keep using css/styles.css; this file does not affect them.
