   solution-hero-motion.css
   CBC SOLUTION HERO MOTION SUITE  (shared framework, 9 pages)

   WHAT THIS IS
     The suite-wide generalisation of the approved Capital Strategy & PMO
     large-motion prototype (assets/css/construction-heroes.css, section 6).
     It carries the same approved behaviour to the remaining nine solution
     heroes — four Construction, five Enterprise — from one stylesheet:

       - one large right-half composition on a 620 x 360 canvas
       - a single one-time phase-in of exactly 4s, slightly slow and smooth
       - fully resolved for ever afterwards: no loop, exit, bounce, spin or
         pulse anywhere in the file
       - reduced motion renders the resolved end state, statically
       - the figure is hidden at <= 900px by the existing shared rule

   WHY CAPITAL IS NOT IN HERE
     The Capital prototype is the approved appearance/timing reference and is
     left byte-identical in construction-heroes.css. This file never selects
     .enthero--con-capital, so that page cannot be altered by loading it.

   ARCHITECTURE
     Two orthogonal axes, so each page needs geometry only, not CSS:

       PAINT class   what the object looks like and how it moves
                     .shm-block .shm-frame .shm-dot   -> rise family
                     .shm-gate                        -> scale family
                     .shm-line (+ --spine --route --mark) -> draw family
                     .shm-line--soft                  -> soft-draw family

       STAGE class   when inside the shared 4s it resolves
                     .shm-s1 ... .shm-s6  (earliest -> latest)

     Per-object nudges use inline custom properties only:
       --shm-fx / --shm-fy   entry offset for the rise family
       --shm-d               0-200ms intra-stage stagger

   SCOPE
     Everything is scoped under .enthero--shm, a private class added to the
     nine hero <section> elements. No selector here can reach any other
     animation on the site, and no @keyframes name is reused from
     enterprise-heroes.css or construction-heroes.css (all are shm-*).
