/* ==========================================================================
   s35-rsync.css — the rsync case-study page (/rsync.html)
   --------------------------------------------------------------------------
   Section builder for the rsync case study. Colour comes ONLY from shell
   tokens (--paper --card --ink --ink-rgb --ink-60 --muted --hair
   --hair-strong --pass --fail --stale --unknown --signal --radius --mono
   --prose), so all eight themes follow. Rails come from s35-craft.css.
   Motion reuses the shell arrival system only: [data-reveal], .fx, .dr with
   --d/--dur. No script. 12px floor everywhere.
