/* Little Words — games/shared/matrix-engines.css
   Layout shared by the four config-driven matrix engines: memory_match,
   feed_the_character, builder_assembly, this_or_that. Theme colours arrive as
   CSS custom properties set per page (--t1..--t4), so one stylesheet dresses
   every theme. Rails baked in: ≥44px targets, mobile-first at 375px, nothing
   overflows the viewport, reduced-motion respected. */
