/* ==========================================================================
   UNTECH d.o.o. — Industrial execution partner
   Design system & stylesheet
   --------------------------------------------------------------------------
   Author: Senior web design / front-end
   Notes:
   - Mobile-first, progressive enhancement.
   - Blue is dominant, muted red is a controlled accent only.
   - No neon, no glow, no saturated gradients. Restrained, mature, industrial.
   - Distinct from PANMONT: condensed display type, large index numbers,
     blueprint grid motifs, diagonal/offset image cropping, asymmetric hero.
