Colors come from shared theme tokens — --surface, --ink, --border, --accent and friends — so this CSS carries no palette of its own. Use Runnable file to copy the tokens along with it.

  display: grid;
  gap: 1px;
  background: var(--border);
  border: 1px solid var(--border);

const tiles = document.querySelectorAll('[data-hss-filter] button');
tiles.forEach((tile) => tile.addEventListener('click', () => {
  const wasOn = tile.getAttribute('aria-pressed') === 'true';
  tiles.forEach((other) => other.setAttribute('aria-pressed', String(!wasOn && other === tile)));
  const state = wasOn ? 'all' : tile.dataset.state;
  document.querySelectorAll('.hss-list li').forEach((row) => {
    row.hidden = state !== 'all' && row.dataset.state !== state;
  });
}));
