/* ════════════════════════════════════════════════════════════════════
   CORPORATE SOCIAL RESPONSIBILITY — "Building A Better Tomorrow" Hero
   Isolated component (see csr-hero.js). Replaces the previous abstract
   particle .csrh hero on csr.html only. Full-bleed photographic
   composition of hands joined over growing seedlings, wooden blocks and
   a green globe (Hero/csr.*) with a single left-to-right scrim carrying
   the headline — one full-inset photo + one scrim, matching the site's
   established hero convention (.op-hero in process-hero.css, .awh in
   awards-hero.css, .ins-hero in blog-hero.css), not a boxed image
   stitched against a separately drawn background. The plate already
   bakes in its own navy field on the left and the orange curve along
   the bottom, so neither is redrawn. A four-item CSR commitment row
   spans the full width of the lower band.

   Motion contract: only transform / opacity are animated on anything
   that runs continuously. Width, height, margin, left and top are
   never transitioned.
