feat(dashboard): cinematic beacon — living arc teaser, sheen title, scrim

The beacon is now a dark cinema card: a small canvas paints a breathing
night-world with golden travel arcs on loop, colored glows drift over it, the
title carries a gold sheen sweep and the copy sits on a bottom scrim. Core
colors ride inline so no dashboard widget CSS can wash the card out again.
