   Scroll-reveal entrance — per-section distinct animations
   ──────────────────────────────────────────────────────────────────────
   The shortcode outputs ONE .appdev-section built from two structurally
   distinct blocks: the heading/intro (.appdev-section__head) and the
   services-cards grid (.appdev-service-card). Each block gets its OWN
   entrance animation. When the shortcode is placed more than once on a
   page the resulting sections are structurally identical, so the animation
   set is ALTERNATED per .appdev-section via :nth-of-type(odd|even) —
   consecutive sections always look different:

     ODD  sections:  heading = slide-from-left   · cards = zoom-pop
     EVEN sections:  heading = slide-from-right   · cards = 3D flip-in

   opacity + transform ONLY — no layout shift, no filter/blur on the
   bordered cards (the flip uses rotateX, a transform). Slow premium
   1.2s cubic-bezier(0.16,1,0.3,1) with staggered cards; the longest
   card (0.82s delay + 1.2s) finishes at ~2.02s, inside the JS cleanup
   window (2.4s), which then strips the classes back to the resting state.
   JS toggles .appdev-reveal / .appdev-in — trigger unchanged.
