/* ============================================================
protoseq.com homepage (approved redesign, 2026-10-07).
Built from homepage-reference.html. The rules below are the
reference's own, in its order, with three changes:
1. --orange moves from an inline style into the token list.
2. The three photo backgrounds are real ![]()
layers (.bg), so
the two below the hero can lazy-load. Same image, same
position, same gradient on top.
3. Additions at the end: the photo layers, the phone menu
(toggleMenu / #mobileMenu in main.js), and the form.
Loaded by index.html only. Other pages keep styles.css.
