/* chriswang.design — base layer.
 *
 * Shared structure for every art direction: reset, tokens, the hero and work index, the scene
 * layer, the chrome (theme toggle, name mark, director switcher), View Transitions and reveals.
 *
 * A direction (styles/directions/<id>.css) overrides tokens for [data-theme="light"] and
 * [data-theme="dark"] independently, and may restyle any selector here. Only one direction
 * stylesheet applies at a time.
 *
 * The user multipliers --u-* come from the ⌘⇧D panel (js/core/params.js); every size here goes
 * through them so the panel works the same in every direction.
 *
 * Cascade: everything here sits in @layer engine, declared first, so any direction rule in
 * @layer base or @layer utilities wins on order alone, with no specificity contest and no
 * !important. The one exception is the reduced-motion block: an !important inside the
 * earliest layer outranks every later layer, which is exactly the guarantee it needs.
