/* Protween — landing site
 *
 * Design rules baked in here:
 *   - Single accent (CSS var) so a future palette swap is one line.
 *   - No blue/purple gradients, no glassmorphism, no neon glow, no
 *     deep blur shadows, no glowing buttons. Borders are 1px solid,
 *     shadows are flat & subtle.
 *   - Bg = white. Foreground = near-black. Hierarchy via type weight
 *     and size, not via color noise.
 *   - Accent currently deep forest green; the brand color isn't
 *     final, swap `--accent` and `--accent-hover` only.
