/* =====================================================================
   mobile.css — phone density layer  (phones ONLY; desktop is untouched)
   ---------------------------------------------------------------------
   Loaded after style.css. Everything visual lives inside max-width media
   queries, so >= 992px renders exactly as before.

   Goal: compact. The phone landing page was 16,091px tall at 390px
   (~19 screens) because every card grid collapsed to one column, sections
   kept 64px paddings, buttons were sized for a desktop hero, and the
   featured-research PDF was an <iframe> — which iOS Safari cannot scroll
   (it shows page 1 and stops).

   Rules of the layer:
     * two- and three-up grids instead of one card per row
     * small buttons, tight line-heights, small type
     * no decorative empty space: halved section rhythm, small gaps
     * jump-to-section menu stays available on phones
