/* ===========================================================================
   SolutionsCoding -- 特長: alternating rows (framed AVATAR CODING window +
   text column), the shared mini-window vocabulary, crops 01 (スキル) and 02
   (エージェント). Port of the ChatOps .co-feat rows with this page's names.
     coding-feat-2.css  crops 03-05, caption, terms, and ALL motion of the
                        特長 + 選ばれる理由 crops (one vocabulary, one file)
     coding-why.css     選ばれる理由 band + rows + micro-windows
   The window reuses the hero's visual language (coding-hero*.css): navy bar,
   orange brand tile, tinted request bubble, the green check. Nothing inside
   a crop is clickable: no border-on-hover, no hover at all (aria-hidden).
   Every rule here is a FINAL frame; start states live in coding-feat-2.css
   under html.cd-motion [data-cd-latch]:not(.cd-seen) only.
   Type floor (owner rule 2026-10-04): Japanese >= 13px, Latin >= 12px.
   Inside the windows: titles 14px, bubbles / labels 13px, brand / code 12px.
