/* =============================================================================
   Shared palette for every page on the site.

   Light is the primary design and is defined on bare :root, so nothing depends
   on a media query resolving. Dark redefines only the tokens.

   This lives in one file on purpose. Two hand-synced copies of a palette drift
   apart — one page gets a new token, the other does not, and the mismatch only
   shows up in whichever colour scheme you were not looking at.

   There is deliberately no [data-theme] override: the site has no theme toggle,
   so such a block could never match.
