   THEMES
     :root            -> dark (default)
     [data-theme=light] -> light

   Toggle in JS:
     document.documentElement.dataset.theme = 'light' | 'dark'

   COLOR MODEL
     All colors are oklch() so lightness/chroma stay perceptually
     even when you re-hue the brand. Change --brand-h to re-skin.
