/* ============================================
   BRIGHT FUTURES FOUNDATION — SHARED STYLES
   Version: 1.0
   Updated: May 2026

   Single source of truth for all pages.
   Covers: design tokens, reset, nav, footer,
   buttons, typography classes, reveals, and
   responsive breakpoints.

   Page-specific styles (hero, sections) live
   in each page's own <style> block or a
   separate page-level CSS file.
