/* Basim Estimate — premium/tactile construction-tech UI.
   Steel accent on a warm-grey ground, Barlow Condensed over Barlow.
   Elevated cards, recessed input wells, substantial touch targets.
   The printed proposal keeps the drafting language: hairlines and
   registration marks, with every radius and shadow reset for paper. */
