/* Methodology page (templates/web/method.html), Edmon 12 Oct 2026: calm, large type, one picture per chapter.
   Motion: only transform / opacity (smooth), eased like iOS. Every picture's FINISHED state is the default; the
   starting states apply only under .mth-js (JavaScript on) and before the chapter gets .in. With "reduce motion"
   nothing moves. Colours are the site's day/night tokens, so both modes work without extra rules. */
