/* ---------- Tokens ----------
   Every visual value lives here. Components reference tokens, never raw numbers.
   Layer 1 (scales) defines the raw steps; layer 2 (roles) maps them to intent.
   Change a scale step to shift everything that uses it; change a role to
   repoint one kind of element (e.g. all cards) to a different step.

   Breakpoints can't be custom properties inside @media, so they're listed here
   and used literally: 40rem (header stacks; 2-col work grid), 52rem (side-by-side
   layouts), 60rem (3-col work grid), 75rem (banner wraps). */
