   vowlt — the one stylesheet. Order: tokens → base → controls → shell →
   forms → messages → lists → motion → pages. Every colour is a token and
   every token is a light-dark() pair, so nothing below the tokens knows which
   theme it is in. One column, one width, on every page: the rail sits beside
   it on a wide screen and becomes the bottom bar on a phone.
