/* ==========================================================================
   Dongding Machinery — Homepage stylesheet
   Plain CSS (production will be SCSS with the same BEM structure).
   Naming: BEM (block__element--modifier). No atomic/utility class stacking.

   Units: rem-based. The root font-size (html) scales with the viewport, so
   every font / spacing / size / image dimension scales proportionally.
   Base: 1rem = 10px (html 62.5%). Border 1px and media-query breakpoints
   stay in px on purpose.
