/* ============================================================
   THEME — Press
   -----------------------------------------------------------
   This is the ONE FILE users swap to reskin their site.
   Replace this file with any other theme.css to change the
   entire look & feel. Tokens only — no component CSS lives here.

   Mood: T-Magazine / Stripe Press / Apple Newsroom editorial
   newsprint. Classical measure, thin hairlines, dramatic serif
   display, a single press-red accent. Warm off-white paper,
   near-black ink, very square radii, minimal flat shadows.

   TOKEN CONTRACT
   -----------------------------------------------------------
   Every theme MUST declare every variable in this file, even
   if it sets it to a neutral value (e.g. --blur-md: none;).
   That's what guarantees a clean one-file swap.
