/*
 * VantaTrack — vantatrack.io
 *
 * The system is the one the owner pinned: soft-gray ground, pure-white cards,
 * pure-black ink and actions, and exactly one accent. Four colours, nothing
 * else. Inter at three weights. Everything that can be a pill is a pill, cards
 * are large-radius, and the only colour that carries any area is a soft wash of
 * the accent inside white.
 *
 * The accent is ours, not the reference's: #00ff9d, straight out of the ring in
 * the VantaTrack mark. That single substitution is what makes this our page
 * rather than a copy of theirs.
 *
 * Depth is a hairline and a large radius. There are no drop shadows.
