/* ==========================================================================
   NeoGenesis Capital — mobile / narrow-viewport layout (≤ 900px)
   The desktop page is authored on a fixed 1440px stage that is scaled to fit. Below 900px that scale makes
   the type unreadable, so the stage (Hero → Platform) is swapped for the normal-flow `.m-stage` markup in
   index.html, and the flow sections (Momentum, Press, Portfolio, Leadership, footer) get tighter rules.
