   your design is taller than the visible area - so you can add as many/long sections as you
   want and just scroll down to keep working, nothing gets clipped or cut off.
   IMPORTANT: we do NOT force height:100% here. #gjs *is* the ".gjs-editor" element (GrapesJS
   adds that class directly onto the container we pass in), and it already gets an explicit
   inline height from email-designer.js (height: calc(100vh - <offset>px)). A height:100%
   !important rule on .gjs-editor would override that inline style (important beats inline)
   and instead ask for 100% of .designer-card, which has no defined height of its own - an
   indeterminate reference that different browsers/window sizes resolve inconsistently. That
   mismatch is exactly what made the canvas behave in a maximized window but not a normal one.
   Leaving height to the inline style (with the min-height floor below as a safety net) and
   only forcing overflow here lets GrapesJS's own resize logic size the canvas correctly at
   any window size. */
