/* Scale Summary — layout + sidebar styles
   Auto-served by Dash from /assets/. */

/* === Height plumbing ===================================================
   On desktop (>= lg) we plumb height through Dash's nested page-container
   chain so the sidebar can fill the viewport.

   On mobile we DELIBERATELY drop this chain — letting .ss-page take its
   natural height — so the page can scroll the whole way down through the
   stacked sidebar + plots. Without this, the natural sidebar height
   collapses the content area (and therefore the plots) to ~0.

   DOM chain (top → down):
     #page-content-wrapper  (style: flex:1, overflow-y:auto)
       > div                ← dash.page_container outer, no id/class
         > #_pages_content  (Dash internal)
           > .ss-page       ← us
