  ── EVOLVING TO A GLITCH AESTHETIC ───────────────────────────────
  The site is built on CSS variables so the look can shift quickly.
  Search for "GLITCH:" comments throughout — each marks a ready-made
  option you can uncomment or tweak:
    • Neon accent colors (change --accent)
    • Scanline overlay  (body::after, below)
    • Glitch split text  (hero h1 + .glitch in section 5)
    • Random flicker     (js/main.js, bottom of file)
