/* ============================================================
   NTM — Defining Moments

   Editorial photo-submission showcase. Reuses the homepage/about
   token contract from theme.css (never hardcode brand colors).

   Section rhythm:
     1. Hero       — dark (#161616), teal eyebrow + serif headline + glow
     2. Gallery    — paper bg, editorial 2-col header + responsive card grid
     3. Pull-quote — dark band, large serif quote
     4. CTA        — cream band, teal button (mirrors the About CTA)
     + Lightbox    — minimal dark overlay (driven by defining-moments.js)
