   PALETTE SYSTEM
   Each brand palette defines: ink / paper / surface tints / accent /
   accent-on-dark / a secondary accent. The light/dark toggle swaps
   which of {ink, paper} is background vs text. The "inverse band"
   (.band-dark) always uses ink-on-paper regardless of toggle — this
   is a deliberate art-direction choice (dark hero/CTA sections),
   independent of the accessibility light/dark preference.
