 * RaASaAD Mobile Results Overhaul 2026

 * Mobile is treated as a first-class product surface rather than a scaled
 * desktop layout. The existing desktop components remain untouched; this
 * layer owns viewport rhythm, touch targets, card hierarchy, chat docking,
 * safe-area handling and horizontal-overflow prevention below 760px.
