/* AM Lab — 21tsi.com-style look: deep SU navy (not black), Switzer light display, Southern University gold hero with navy text.
   SU colors (SU Visual Style Guide, Oct 2024): Gold #FFC72C (light #FFD45C, deep #E0A91F, darkest #B8860B), Columbia Blue #69B3E7, Navy #00263A.
   Dark surfaces use navy and its darker tints (#00263A, #001A29, #00131F). Columbia Blue: links/hover, focus rings, progress line, small accents.
   Rule (client, Oct 24 2026): everything that was orange is SU Gold, never blue.
   Design tokens live in <style id="tokens"> in index.html so /tweak can edit them. */
