/* MNEOS Wave-2 restructure — 2026-07-29
 *
 * New component classes only. No refactor of existing rules.
 *   1. Hero H1 contrast fix + Build Status orphan-row fix (rebalance overrides)
 *   2. How MNEOS works — reasoning-loop diagram + three principles
 *   3. Explore MNEOS — four gateway tiles (deliberately distinct from .r-card)
 *   4. Work with MNEOS — audience self-identification grid
 *   5. /why-mneos/ Chapter 2 — chapter opener, bridges, closing
 *   6. /platform/ — page opener
 *
 * Palette is the established site palette in styles.css :root
 *   ground #0B0D0F · card #171A20 · border #232830 · ink #F3EFE7
 *   dim #C4BDAE · accent #4A7DFF · signal #6FCF97 · copper #B9724A
