/* ===========================================================================
   SolutionsCoding -- 選ばれる理由: photo band + ruled reason rows, each with a
   flat AVATAR CODING micro-window (264x136, aria-hidden decoration; sized for
   the type floor: Japanese 13px, Latin 12px).
   Port of the ChatOps .co-why rows. Colour tokens, the check (.cd-feat-ck)
   and the motion vocabulary (.cd-feat-in / .cd-feat-pop) come from
   coding-feat.css / coding-feat-2.css. Final frame = default; start states
   only under html.cd-motion [data-cd-latch]:not(.cd-seen).
   No .dc-term lives in this section, so the rising titles / texts never hold
   a popover.
