/* ===== Base ===== */
/* Original background color: #fdfaf4
Recommended background colors:
#ffffff — Pure white. Clean and minimal, standard for academic pages.
#f5f5f5 — Cool light gray. Neutral and modern, very common in tech/research sites.
#f7f8fa — Light blue-gray. Subtle cool tone, feels sleek and contemporary.
#f0ede6 — Warm gray. Similar warmth to your current cream but less yellow, more sophisticated.
#f5f7f2 — Light sage. Very subtle green undertone, feels fresh and distinctive.
#fafafa — Near-white. Almost pure white but slightly softer on the eyes. */
