   below the map (measured: only a partial reduction, 2070px -> ~1503px,
   still ~863px taller than the map) but by adopting the pattern 4 of 6
   comparable tools already use (postcode-mapper/route-optimiser/
   flood-risk/nearest-postcodes's own `.tool-container { max-height:
   700px }` + `.tool-sidebar { overflow-y: auto }`) - the SAME 700px
   value, not invented here. Applied to the sidebar directly rather than
   the `.tm-layout` grid container: those four tools cap the flex PARENT
   because a flex child's overflow only clips within a bounded parent,
   but `.tm-layout` is a CSS grid with `align-items: start` (deliberately
   NOT stretch, so the 640px map is never force-stretched to match a
   taller sidebar) - capping the grid ITEM directly is the grid-native
   equivalent of the same mechanism, same value, same effect. Desktop
   only: reset inside the existing mobile breakpoint below, where the
   layout already stacks map above sidebar and a second, nested scroll
   region inside a single narrow column would be worse, not better. */

   move was for, without inventing a layout no other tool in the estate
   uses - checked directly, all 6 comparable tools keep every panel

   own Export section (the one other real export feature in the estate)
