/* ARAS ENERGY — main-service pages (solar · BESS · engineering · consulting).
   Loaded only on the four main-service pages under /services/.

   Entry animations: services.js adds .is-playing to a [data-play] block once
   it is in view. Every a-* class below is inert until then, and only when the
   page runs JS (.svc-js) does a block start from its first frame — without JS
   the final drawing simply shows. Drawn strokes use pathLength="1", so one
   dash of length 1 is the whole path whatever its real length. */
