/* ============================================================================
   Swayam Shipping — shared UI system
   Linked by every tool page (SI Generator, SB Verification, B/L Creator) so the
   suite shares one visual language and can never drift apart. Page-specific
   components (report tables, container tables, history rows, etc.) stay in each
   page's own <style> block; only the common foundation lives here.

   Fonts are self-hosted from /static/fonts (no dependency on Google's CDN, so
   the design survives offline / firewalled office networks). Brand colours are
   the mandated Deep Logistics Blue / Golden Amber / Platinum Gray; everything
   else is a supporting extension kept a shade apart from those three.
   ========================================================================== */
