/*
 * Nexus.
 *
 * The page has one job -- get you into another service in under two seconds --
 * so the visual budget goes on legibility and on making the target obvious, not
 * on decoration for its own sake. Three effects carry the whole thing:
 *
 *   1. a slow aurora wash behind everything, so the page has depth at rest;
 *   2. a cursor-tracked spotlight on the hovered card, so the thing under your
 *      pointer lights up before you have consciously aimed at it;
 *   3. per-service accent hues, held almost fully desaturated until hover.
 *
 * That last restraint is the whole trick. Sixty saturated tiles is a toybox;
 * sixty quiet tiles where only yours has colour is a tool. Every effect here is
 * transform/opacity only and sits behind prefers-reduced-motion.
