/* =============================================================
   NIGHT BRIGHT — styles.css
   Custom styles that complement Tailwind (CDN).
   Tailwind handles layout/spacing/colors via utility classes;
   this file owns the brand "motifs" Tailwind can't do cleanly:
   the gold headlight glow, the starburst, the before/after
   slider, and motion. Everything here is commented so it's
   easy to tweak.
   ------------------------------------------------------------
   Brand tokens live here too (as CSS variables) AND are mapped
   into Tailwind in index.html. Change a color in BOTH spots,
   or just use the Tailwind class names (e.g. bg-crimson).
