/* marketing/css/marketing.css
 * MorphyLearn public marketing site — morphylearn.com (§8, roadmap).
 *
 * Deliberately NOT the app's own hoc.css/wordLab.css files, and this site
 * has zero build tooling (plain HTML, one stylesheet) per §8.2's own
 * explicit recommendation ("even hand-authored HTML/CSS for a first
 * version"). But the PALETTE and TYPE PAIRING below are not invented —
 * they're the real --hoc-* tokens and the real morpheme color coding
 * already live in the product (src/styles/hoc.css, src/styles/wordLab.css):
 * warm off-white surfaces, espresso ink, and the exact green/blue/gold used
 * for prefix/root/suffix in Smash Apart and Mix & Match. A visitor who
 * signs up and lands in the real app should feel zero visual discontinuity.
