/* =====================================================================
   tokens.css — the design system in one file.

   Change the brand here, once, and both surfaces follow. Two surfaces,
   two moods, one set of tokens:
     - The portal (model) uses a calm, light, spacious feel.
     - The dashboard (photographer) uses the same tokens at higher density.

   These are starting values. Make them your friend's — swap the accent,
   the font, the radius. Just keep using the variables instead of
   hardcoding colors all over the app.
