/*
 * Teaching page redesign (2026), aligned with the Cornell ILR visual style
 * ------------------------------------------------------------------------
 * Loaded last on teaching.html and scoped to body.teach-v3, so no other page
 * is affected.
 *  - Palette: white, ink #222, Carnelian #b31b1b. No gradients, no blue or gold.
 *  - Type: Open Sans ExtraBold caps for display (stand-in for ILR Replica) and
 *    Roboto for text (stand-in for Futura). No shadows on type.
 *  - Rounded rectangles (requested), thin rules, no large color fields.
 *  - Motion is limited to parallax, letter lift, reveal and a slow marquee, and
 *    all of it stops under prefers-reduced-motion.
 *  - The ILR logo and open frame are not used.
