   Markup contract (rendered by app.js / index.html shell):
     <div class="ad-slot" data-ad-slot="<name>" hidden></div>

   STATES (driven by ADS_CONFIG in app.js):
   • default  (enabled:false, preview:false) — slot keeps `hidden`:
     display:none, ZERO space, ZERO layout shift, ZERO requests.
   • enabled  (enabled:true + slot `code` set) — `.ad-live`: the pasted
     network code renders fluidly, centered, capped per breakpoint.
   • preview  (preview:true) — `.ad-preview`: a dashed labeled box for
     layout QA. Pure CSS text — NEVER fires external requests.

   No external URLs, no fetch/XHR anywhere in this layer.
