/* Workforce Pipeline widget (v2).
   Light card. Three-stage pipeline (SOURCED → TRAINED → PLACED) with
   a single teal pulse traveling the rail and the three Watts-to-
   Workers source programs named below. Matches the vocabulary of
   stage-path + sovereign-enclave: white card, tinted panel inside,
   mono labels, brand teal accents, soft shadow stack. CSS-only
   motion. Reduced-motion parks the pulse and keeps all counters
   visible. */
