  /* Composed family stacks, referencing the per-role families in font-roles.css.
     Import order is irrelevant because the cascade resolves every :root
     declaration before any substitution happens.

     ⚠️ But substitution happens at computed-value time ON THE ELEMENT CARRYING
     THE DECLARATION — not at each use site. So the stacks below are frozen into
     concrete values here on :root and inherit downward already resolved.
     Re-pointing --font-family-display on a page block or section therefore has
     NO EFFECT, silently: every heading keeps the family resolved at :root.
     Set the role families on the same element that composes them. */
