   Lifted verbatim from the approved prototype. Everything is namespaced under
   .zsp so it cannot collide with the market page's existing styles.

   Two rules here are load-bearing and must not be "tidied":
   - the docked player's 400px width floor (YouTube needs a 200x200 minimum
     viewport and recommends 480x270 for 16:9; below that the controls break)
   - no docking at all below a 520px viewport, for the same reason

   THE BOTTOM DOCK

   The Spotlight moved from above the products to the bottom of the market
   page. Products are the main stage; the feature is a sticker in the corner
   until someone opens it, and then it takes the lower part of the screen
   while the product list keeps scrolling above.

   position: sticky, not fixed. The module is the LAST child of .market-stack,
   so it is pulled up to the viewport bottom while the products scroll past
   and settles into place at the end of the page — no manual offsetting, and
   it cannot strand itself over the footer at the end of the document.

   .zsp--docked is added by spotlight.js, never in the markup. With no JS the
   module renders in flow, whole, at the end of the page: crawlers and share
   cards read the same HTML they always did, and no content is collapsed
   behind a control that cannot run.

   SILENT-FAILURE CONSTRAINT: sticky needs every ancestor of .zsp to leave
   overflow alone. The chain is .market-stack -> body (gear.html empties
   base.html's container_wrap). mobile-responsive.css sets
   `body { overflow-x: hidden }`, which is safe only because nothing sets
   overflow on `html` — the used value then propagates to the viewport and
   body stays a non-scroller. Put overflow on html and this pins nothing,
   with no error anywhere.

   video alone is taller than the display. Capping the dock cannot fix that;
