   MOBILE STACKED-DIAGRAM VOCABULARY (.dgm-desk / .dgm-mob swap + .mdg-* cards)
   ────────────────────────────────────────────────────────────────────────────
   PURPOSE: re-express a dense inline-SVG figure as a clean VERTICAL stack of
   HTML cards on phones (≤760px) — every label & the diagram MEANING preserved,
   fully legible, in the OCSS neutral-light brand. DESKTOP IS UNTOUCHED: the
   .mdg-* card styles exist globally but only render because .dgm-mob is hidden
   on desktop (display:none) and only flips to block at ≤760px. Nothing here
   alters any desktop layout.

   MARKUP PATTERN (page agents tag each figure):
     <figure class="fig dgm-desk"> …existing desktop <svg>… </figure>
     <div class="dgm-mob"> …stacked .mdg cards mirroring the same nodes… </div>

   Reuses the SAME icon sprite as the SVG diagrams: <svg class="mdg-ico"><use
   href="#ic-rules"/></svg> (ids #ic-rules #ic-dns #ic-router #ic-device
   #ic-browser #ic-apps #ic-ocss #ic-seal #ic-envelope #ic-app …).
