/* ==========================================================================
   style.css — BGS Public Site UI Foundation
   --------------------------------------------------------------------------
   This file replaces the previous placeholder style.css (which only defined
   an unused .hero-section/.info-section pair pointing at a missing image —
   see PROJECT_ANALYSIS.md §10/§11). Nothing in the live site linked the old
   content, so nothing breaks by replacing it here.

   Structure:
     1. Font import
     2. Base / reset
     3. Typography system
     4. Utility classes
     5. Reusable components (consolidated from page-level inline <style> blocks)

   NOTE: this file is NOT yet <link>ed from any page/header. It is a staged
   foundation — wiring it in is a follow-up step once approved, per the
   "do not edit PHP/HTML" constraint for this pass.
