  /* ── ADS project binding — contract role aliases ──────────────────
       Additive only: aj-site keeps every declaration above unchanged and
       keeps its current look (light theme, blue accent). These aliases let
       the file "speak" the Arcadia Design System contract (see
       docs/design-system/02-tokens.md) by pointing each contract role at
       aj-site's own values — a project binding, not a core theme, in the
       External family's warm/personable register applied to the roles
       aj-site didn't already define (text-3/4, border-strong). Zero visual
       change: nothing below is consumed by any existing rule in this file.
       Swapping aj-site to the External core theme later is a one-block
       value swap, not a rewrite. */
